| CVE-2026-99067 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: btrfs: scrub: fix local_root reference leak in scrub_print_warning_inode() When paths_from_inode() fails, scrub_print_warning_inode() jumps to err without dropping the reference taken by btrfs_get_fs_root(), leaking a reference to the root every time path resolution fails while printing scrub warnings. Every other error and success path of the function drops the reference. Drop the reference on the paths_from_inode() failure path too. | ||||
| CVE-2026-99068 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ALSA: ctxfi: Fix memory leakage when clearing DAO input mappers Commit e576e7843c0d ("ALSA: ctxfi: Simplify dao_clear_{left,right}_input() functions") centralized the DAO input mapper clearing logic in dao_clear_input(), but omitted the kfree() calls. It removes the mapper entries from the list and sets their pointers to NULL without freeing the allocated array. This leaks memory each time dao_clear_input() is called. Store the base pointer of the allocation before clearing the mapper entries and free the array after removing entries from the list. | ||||
| CVE-2026-99080 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: fs: Free any excess xarray nodes in clear_inode() For many years we've had a hard to hit leak of xarray nodes. Hugh documented it well in commit 786b31121a2c. Recently people and syzbot have found ways to force it to happen with madvise. Rather than fix the leaks where they happen, just call xa_destroy() which has the side-effect of cycling the i_pages lock. | ||||
| CVE-2026-114613 | 1 Msgpack | 1 Msgpack-python | 2026-10-23 | 7.5 High |
| MessagePack is the serializer implementation for Python msgpack.org. Prior to 1.2.3, the msgpack-python C extension (msgpack._cmsgpack) leaks a decoded map value when deserialization rejects a key with strict_map_key=True (the default). Repeated malformed inputs can cause unbounded process memory growth and denial of service in applications that deserialize attacker-controlled MessagePack data. Both unpackb() and the streaming Unpacker API are affected. The pure-Python fallback does not exhibit this leak in the reported tests. This issue is fixed in version 1.2.3. | ||||
| CVE-2026-99046 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: gve: fix XSK buffer leak on error descriptor When the error bit is set in the RX completion descriptor, the buf_state and its attached buffer should be freed. In the case of AF_XDP ZC, the XSK buffer was not freed, leading to a leak. This issue was caught by LLM. | ||||
| CVE-2026-99047 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: gve: fix XSK buffer leak when rings are stopped GVE does not free XSK buffers when resetting ring state as a part of stopping queues. This causes all XSK buffers which are posted to the NIC to be leaked. Free XSK buffers attached to an allocated buf_state when stopping rings. This issue was hit in production. | ||||
| CVE-2026-98949 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: drm/imagination: Fix reference and vm_bo handling in remap() When a map overlaps part of an existing mapping, pvr_vm_gpuva_remap() splits the mapping into prev/next parts covering what the request did not take, instead of creating something new. It gets two things wrong. - A GEM reference is taken for each part but it's never needed and never dropped, so it leaks one reference per split (remap-next-in-2m in tests/imagination/pvr_vm_map.c): CRITICAL: 33558528 bytes of shmem still held after close - The parts still belong to the original object being split, but pvr_vm_gpuva_remap() links them to ctx->gpuvm_bo, the new object's vm_bo: prev_va --obj--> BO_A BO_B <--obj-- vm_bo (ctx->gpuvm_bo) \___________link___________/ (mismatch: BO_A != BO_B) drm_gpuva_link() catches the mismatch: WARNING: drivers/gpu/drm/drm_gpuvm.c:2108 at drm_gpuva_link+0x2ec/0x310 drm_WARN_ON(obj != vm_bo->obj) Call trace: drm_gpuva_link pvr_vm_gpuva_remap __drm_gpuvm_sm_map pvr_vm_map pvr_ioctl_vm_map Link them to op->remap.unmap->va->vm_bo instead. The locking of the GPUVA lists of the other objects touched by a split is not addressed here; it is handled by switching the GPUVM to immediate mode. | ||||
| CVE-2026-98962 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: btrfs: free iov when btrfs_uring_read_extent() fails After btrfs_uring_read_extent(), the caller always jumped to out_acct. That skips kfree(data->iov), which is only correct for -EIOCBQUEUED where the deferred path owns the iov. On failure, fall through to out_free instead. | ||||
| CVE-2026-99019 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: scsi: ch: Do not keep references to data transfer element devices ch_readconfig() looks up the scsi_device of every data transfer element whose SCSI id the changer reports in READ ELEMENT STATUS, and stores it in ch->dt[]. scsi_device_lookup() takes a reference, and nothing ever drops it: ch_destroy() frees the array with kfree(). ch->dt[] is read nowhere else - it only supplies the vendor, model and revision printed in the same loop. Once such a drive is removed, its scsi_device can never be released. It stays on the host's device list at its address, so a new device there is refused by anything that walks the list - target_core_pscsi reports "scsi_device_get() failed for H:C:T:L" - and the low-level driver's module can no longer be unloaded. Only a reboot recovers. It shows with any changer that reports its drives' ids; with the mhvtl virtual library (IBM 3573-TL personality), each create and remove of a library with four drives leaves four references behind, counted by the module's use count in lsmod. With ch not bound the count is unchanged, and with this patch applied it is unchanged too. Drop the reference as soon as the name has been printed, and remove the now unused dt[] array. That also removes the array leaked when ch_probe() fails after ch_readconfig(). The same leak was reported with an RFC patch in 2022, which was not merged. | ||||
| CVE-2026-99028 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: net: xilinx: axienet: Free outstanding DMA buffers on dmaengine stop In the dmaengine path the driver pre-submits RX buffers and holds in-flight TX buffers whose SKBs are DMA-mapped by the driver and freed only in the completion callbacks. On ndo_stop() dmaengine_terminate_sync() aborts these descriptors without running their callbacks, and the driver then frees only the ring shells, leaking every SKB still owned by the engine and its DMA mapping on each ifdown. With 128 RX buffers pre-posted per channel, the mapping leak can eventually exhaust a limited IOMMU aperture. Clear the slot's skb in the TX and RX callbacks so a non-NULL skb marks a slot that still owns a live, DMA-mapped buffer, and on stop unmap and free every such buffer. axienet_dma_rx_cb() runs from the DMA tasklet and re-arms the RX ring on each completion, so it can race axienet_stop(): a completion may submit a fresh buffer after dmaengine_terminate_sync() has returned, leaving the channel armed with a buffer the teardown then frees while the engine may still write into it (dma_release_channel() does not stop it either). Add a lock that axienet_dma_rx_cb() holds across the @stopping check and the resubmit, and axienet_stop() holds to set @stopping before terminating. Once @stopping is set no callback can arm a new buffer, and any armed just before is aborted by the terminate, so teardown only frees buffers the engine no longer owns. | ||||
| CVE-2026-98092 | 1 Linux | 1 Linux Kernel | 2026-10-23 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: ASoC: amd: yc: fix memory leak in acp6x_pdm_dma_close() acp6x_pdm_dma_close() does not free the runtime->private_data buffer allocated in acp6x_pdm_dma_open(). Add the missing kfree. | ||||
| CVE-2026-98944 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: HID: steam: Refactor registration This refactors and simplifies the registration/unregistration flow. Since we now only perform registration when the client isn't opened anymore, the logic for handling that can be removed, and the rest of the function streamlined. We also remove the previous assumption that we have a serial number to show we're registered, replacing it with a single purpose boolean. In a previous refactor the code for unregistering a battery if later registration steps failed was accidentally left out. As a result, a lingering power_supply object could get left over after the steam object was torn down. This is also fixed here. | ||||
| CVE-2026-98947 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: vsock: Fix memory leak in vmci_transport_recv_dgram_cb() During the closure of a datagram socket, the vmci_transport_recv_dgram_cb() function may be called, which will add the packets to the socket's backlog; then, after the receive queue is cleared, the __release_sock() function will move the packet back from the socket's backlog to the receive queue, which will lead to a memory leak. sock_close __sock_release __vsock_release // take ownership by user-space lock_sock_nested sock_set_flag(sk, SOCK_DEAD) vmci_transport_release vmci_dispatch_dgs vmci_datagram_invoke_guest_handler vmci_transport_recv_dgram_cb sk_receive_skb if (!sock_owned_by_user(sk)) [...] (!) else if sk_add_backlog() [...] (!) skb_queue_purge(&sk->sk_receive_queue) release_sock __release_sock // move all packets from the backlog // to the receive queue (!) sk_backlog_rcv vsock_queue_rcv_skb [...] __sock_queue_rcv_skb if (!sock_flag(sk, SOCK_DEAD)) // Since the socket is "dead", the function will not // be called sk->sk_data_ready(sk) sock_release_ownership(sk); sock_put Add a receive queue cleanup in the socket destructor to fix this. syzkaller report: unreferenced object 0xffff8880117bfb80 (size 240): comm "irq/56-vmw_vmci", pid 205, jiffies 4295064448 (age 73.992s) hex dump (first 32 bytes): 78 dc 26 1e 80 88 ff ff 78 dc 26 1e 80 88 ff ff x.&.....x.&..... 00 00 00 00 00 00 00 00 c0 da 26 1e 80 88 ff ff ..........&..... backtrace: [<ffffffff82be8d97>] __alloc_skb+0x287/0x330 net/core/skbuff.c:505 [<ffffffffa114bcbd>] vmci_transport_recv_dgram_cb+0xbd/0x210 [vmw_vsock_vmci_transport] [<ffffffffa05072c6>] vmci_datagram_invoke_guest_handler+0x366/0x450 [vmw_vmci] [<ffffffffa050ad75>] vmci_dispatch_dgs+0x235/0x490 [vmw_vmci] [<ffffffffa050b025>] vmci_interrupt+0x55/0x290 [vmw_vmci] [<ffffffff8137ad2b>] irq_thread_fn+0x8b/0x1a0 kernel/irq/manage.c:1205 [<ffffffff8137c7ae>] irq_thread+0x28e/0x530 kernel/irq/manage.c:1314 [<ffffffff81253dd6>] kthread+0x2e6/0x3a0 kernel/kthread.c:376 [<ffffffff81004392>] ret_from_fork+0x22/0x30 arch/x86/entry/entry_64.S:295 Found by InfoTeCS on behalf of Linux Verification Center (linuxtesting.org) with Syzkaller. | ||||
| CVE-2026-98953 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: devlink: fix devlink_rel reference leak when notify work is pending devlink_rel_nested_in_notify_work_schedule() takes a reference on the devlink_rel for the notify work and then queues the work, ignoring the return value of schedule_delayed_work(). If the work is already pending, nothing new is queued, the work runs only once and drops only one reference, so the extra one is leaked together with the devlink_rel and its index in devlink_rels. This is easy to hit. devl_register() of a nested instance queues the work, and if the instance is unregistered before the work has run, devlink_rel_put() queues it again while it is still pending. The work also keeps rescheduling itself for as long as the parent devlink lock cannot be taken, which widens the window. Registering and unregistering a nested devlink instance 100 times while holding the parent lock leaks all 100 devlink_rel objects. The reschedule path in devlink_rel_nested_in_notify_work() has the same problem: if the work was queued again while it was running, the reference it holds is never dropped. Drop the reference in both places when the work was already pending. The pending work holds its own reference, so this can not be the last one. | ||||
| CVE-2026-98913 | 1 Linux | 1 Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: net: thunderx: fix PTP device ref leak in nicvf_probe() cavium_ptp_get() acquires a reference to the PTP PCI device through pci_get_device(). If any initialization step fails after cavium_ptp_get(), the PTP PCI device reference is leaked. Add a common error path to release the PTP reference before returning from probe failures. | ||||
| CVE-2026-98966 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: bonding: fix the program leak when XDP is replaced We need to release the reference on the old BPF prog, whether we are going to no-prog, or replacing the prog with another. Spotted by AI while running tests for the propagation series (leaked programs were accumulating). Selftest will come in the net-next series to avoid conflicts. | ||||
| CVE-2026-99026 | 1 Linux | 1 Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: net: team: free skb when broadcast has no txable port bc_transmit() sends the original skb through the last txable port. When no port is txable, it returns false without consuming the skb, but team_xmit() still returns NETDEV_TX_OK. AF_PACKET sends then retain the skb and its socket write-memory charge. A TX-enabled, link-down port keeps the broadcast transmit op installed. Carrier can stay up through a second link-up, TX-disabled port or be forced on by userspace. Free the original skb on the no-port path while leaving the existing drop accounting intact. Discovered by Sashiko during review of previous commit. | ||||
| CVE-2026-98948 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: mlxsw: spectrum_flower: Fix port range register leak in tmplt_create() mlxsw_sp_flower_tmplt_create() parses a flow_cls_offload template into a stack-local struct mlxsw_sp_acl_rule_info purely to compute rulei.values.elusage. Parsing can acquire port range registers via mlxsw_sp_flower_parse_ports_range(), but since this rulei never goes through mlxsw_sp_acl_rulei_destroy(), those registers were never released, including through chain template deletion. Factor out of mlxsw_sp_acl_rulei_destroy() the code to actually release the necessary resources and call from mlxsw_sp_flower_tmplt_create() to plug the leak. The issue was found during a review of Wentao Liang's patch referenced below. | ||||

| CVE-2026-99010 | 1 Linux | 1 Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: free the skb when the DLC has no owner rfcomm_recv_data() hands the skb to d->data_ready() and returns 0 without freeing it, so the callback owns the skb from that point on. The tty implementation frees it when the DLC has been detached from its device: static void rfcomm_dev_data_ready(struct rfcomm_dlc *dlc, struct sk_buff *skb) { struct rfcomm_dev *dev = dlc->owner; if (!dev) { kfree_skb(skb); return; } The socket implementation returns without freeing it, and the skb is leaked. A connected DLC can have no owner: rfcomm_sock_destruct() clears d->owner, while the DLC itself stays on the session until it is closed. Data frames that arrive in that window still find d->state == BT_CONNECTED in rfcomm_recv_data() and are handed to the callback, one leaked skb each. The leak does not stop on its own either. The remote runs out of credits only once RFCOMM_RX_THROTTLED is set, and for a socket the only place that sets it is rfcomm_sk_data_ready() itself, below the return. rfcomm_process_dlcs() keeps granting credits, so the remote keeps sending and the leak keeps growing. Free the skb, as the tty side does. | ||||
