CVE-2024-46845 1 Linux 1 Linux Kernel 2025-05-04 7.8 High
In the Linux kernel, the following vulnerability has been resolved: tracing/timerlat: Only clear timer if a kthread exists The timerlat tracer can use user space threads to check for osnoise and timer latency. If the program using this is killed via a SIGTERM, the threads are shutdown one at a time and another tracing instance can start up resetting the threads before they are fully closed. That causes the hrtimer assigned to the kthread to be shutdown and freed twice when the dying thread finally closes the file descriptors, causing a use-after-free bug. Only cancel the hrtimer if the associated thread is still around. Also add the interface_lock around the resetting of the tlat_var->kthread. Note, this is just a quick fix that can be backported to stable. A real fix is to have a better synchronization between the shutdown of old threads and the starting of new ones.
CVE-2024-46844 1 Linux 1 Linux Kernel 2025-05-04 7.8 High
In the Linux kernel, the following vulnerability has been resolved: um: line: always fill *error_out in setup_one_line() The pointer isn't initialized by callers, but I have encountered cases where it's still printed; initialize it in all possible cases in setup_one_line().
CVE-2024-46842 1 Linux 1 Linux Kernel 2025-05-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Handle mailbox timeouts in lpfc_get_sfp_info The MBX_TIMEOUT return code is not handled in lpfc_get_sfp_info and the routine unconditionally frees submitted mailbox commands regardless of return status. The issue is that for MBX_TIMEOUT cases, when firmware returns SFP information at a later time, that same mailbox memory region references previously freed memory in its cmpl routine. Fix by adding checks for the MBX_TIMEOUT return code. During mailbox resource cleanup, check the mbox flag to make sure that the wait did not timeout. If the MBOX_WAKE flag is not set, then do not free the resources because it will be freed when firmware completes the mailbox at a later time in its cmpl routine. Also, increase the timeout from 30 to 60 seconds to accommodate boot scripts requiring longer timeouts.
CVE-2024-46841 1 Linux 1 Linux Kernel 2025-05-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: btrfs: don't BUG_ON on ENOMEM from btrfs_lookup_extent_info() in walk_down_proc() We handle errors here properly, ENOMEM isn't fatal, return the error.
CVE-2024-46840 1 Linux 1 Linux Kernel 2025-05-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: btrfs: clean up our handling of refs == 0 in snapshot delete In reada we BUG_ON(refs == 0), which could be unkind since we aren't holding a lock on the extent leaf and thus could get a transient incorrect answer. In walk_down_proc we also BUG_ON(refs == 0), which could happen if we have extent tree corruption. Change that to return -EUCLEAN. In do_walk_down() we catch this case and handle it correctly, however we return -EIO, which -EUCLEAN is a more appropriate error code. Finally in walk_up_proc we have the same BUG_ON(refs == 0), so convert that to proper error handling. Also adjust the error message so we can actually do something with the information.
CVE-2024-46838 1 Linux 1 Linux Kernel 2025-05-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: userfaultfd: don't BUG_ON() if khugepaged yanks our page table Since khugepaged was changed to allow retracting page tables in file mappings without holding the mmap lock, these BUG_ON()s are wrong - get rid of them. We could also remove the preceding "if (unlikely(...))" block, but then we could reach pte_offset_map_lock() with transhuge pages not just for file mappings but also for anonymous mappings - which would probably be fine but I think is not necessarily expected.
CVE-2024-46837 1 Linux 1 Linux Kernel 2025-05-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: drm/panthor: Restrict high priorities on group_create We were allowing any users to create a high priority group without any permission checks. As a result, this was allowing possible denial of service. We now only allow the DRM master or users with the CAP_SYS_NICE capability to set higher priorities than PANTHOR_GROUP_PRIORITY_MEDIUM. As the sole user of that uAPI lives in Mesa and hardcode a value of MEDIUM [1], this should be safe to do. Additionally, as those checks are performed at the ioctl level, panthor_group_create now only check for priority level validity.

CVE-2024-46834 1 Linux 1 Linux Kernel 2025-05-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: ethtool: fail closed if we can't get max channel used in indirection tables Commit 0d1b7d6c9274 ("bnxt: fix crashes when reducing ring count with active RSS contexts") proves that allowing indirection table to contain channels with out of bounds IDs may lead to crashes. Currently the max channel check in the core gets skipped if driver can't fetch the indirection table or when we can't allocate memory. Both of those conditions should be extremely rare but if they do happen we should try to be safe and fail the channel change.
CVE-2024-46833 1 Linux 1 Linux Kernel 2025-05-04 7.8 High
In the Linux kernel, the following vulnerability has been resolved: net: hns3: void array out of bound when loop tnl_num When query reg inf of SSU, it loops tnl_num times. However, tnl_num comes from hardware and the length of array is a fixed value. To void array out of bound, make sure the loop time is not greater than the length of array
CVE-2024-46832 1 Linux 1 Linux Kernel 2025-05-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: MIPS: cevt-r4k: Don't call get_c0_compare_int if timer irq is installed This avoids warning: [ 0.118053] BUG: sleeping function called from invalid context at kernel/locking/mutex.c:283 Caused by get_c0_compare_int on secondary CPU. We also skipped saving IRQ number to struct clock_event_device *cd as it's never used by clockevent core, as per comments it's only meant for "non CPU local devices".
CVE-2024-46831 1 Linux 1 Linux Kernel 2025-05-04 7.8 High
In the Linux kernel, the following vulnerability has been resolved: net: microchip: vcap: Fix use-after-free error in kunit test This is a clear use-after-free error. We remove it, and rely on checking the return code of vcap_del_rule.
CVE-2024-46828 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-05-04 7.8 High
In the Linux kernel, the following vulnerability has been resolved: sched: sch_cake: fix bulk flow accounting logic for host fairness In sch_cake, we keep track of the count of active bulk flows per host, when running in dst/src host fairness mode, which is used as the round-robin weight when iterating through flows. The count of active bulk flows is updated whenever a flow changes state. This has a peculiar interaction with the hash collision handling: when a hash collision occurs (after the set-associative hashing), the state of the hash bucket is simply updated to match the new packet that collided, and if host fairness is enabled, that also means assigning new per-host state to the flow. For this reason, the bulk flow counters of the host(s) assigned to the flow are decremented, before new state is assigned (and the counters, which may not belong to the same host anymore, are incremented again). Back when this code was introduced, the host fairness mode was always enabled, so the decrement was unconditional. When the configuration flags were introduced the *increment* was made conditional, but the *decrement* was not. Which of course can lead to a spurious decrement (and associated wrap-around to U16_MAX). AFAICT, when host fairness is disabled, the decrement and wrap-around happens as soon as a hash collision occurs (which is not that common in itself, due to the set-associative hashing). However, in most cases this is harmless, as the value is only used when host fairness mode is enabled. So in order to trigger an array overflow, sch_cake has to first be configured with host fairness disabled, and while running in this mode, a hash collision has to occur to cause the overflow. Then, the qdisc has to be reconfigured to enable host fairness, which leads to the array out-of-bounds because the wrapped-around value is retained and used as an array index. It seems that syzbot managed to trigger this, which is quite impressive in its own right. This patch fixes the issue by introducing the same conditional check on decrement as is used on increment. The original bug predates the upstreaming of cake, but the commit listed in the Fixes tag touched that code, meaning that this patch won't apply before that.
CVE-2024-46827 1 Linux 1 Linux Kernel 2025-05-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix firmware crash due to invalid peer nss Currently, if the access point receives an association request containing an Extended HE Capabilities Information Element with an invalid MCS-NSS, it triggers a firmware crash. This issue arises when EHT-PHY capabilities shows support for a bandwidth and MCS-NSS set for that particular bandwidth is filled by zeros and due to this, driver obtains peer_nss as 0 and sending this value to firmware causes crash. Address this issue by implementing a validation step for the peer_nss value before passing it to the firmware. If the value is greater than zero, proceed with forwarding it to the firmware. However, if the value is invalid, reject the association request to prevent potential firmware crashes. Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
CVE-2024-46826 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-05-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: ELF: fix kernel.randomize_va_space double read ELF loader uses "randomize_va_space" twice. It is sysctl and can change at any moment, so 2 loads could see 2 different values in theory with unpredictable consequences. Issue exactly one load for consistent value across one exec.

CVE-2024-46823 1 Linux 1 Linux Kernel 2025-05-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: kunit/overflow: Fix UB in overflow_allocation_test The 'device_name' array doesn't exist out of the 'overflow_allocation_test' function scope. However, it is being used as a driver name when calling 'kunit_driver_create' from 'kunit_device_register'. It produces the kernel panic with KASAN enabled. Since this variable is used in one place only, remove it and pass the device name into kunit_device_register directly as an ascii string.
CVE-2024-46822 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-05-04 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: arm64: acpi: Harden get_cpu_for_acpi_id() against missing CPU entry In a review discussion of the changes to support vCPU hotplug where a check was added on the GICC being enabled if was online, it was noted that there is need to map back to the cpu and use that to index into a cpumask. As such, a valid ID is needed. If an MPIDR check fails in acpi_map_gic_cpu_interface() it is possible for the entry in cpu_madt_gicc[cpu] == NULL. This function would then cause a NULL pointer dereference. Whilst a path to trigger this has not been established, harden this caller against the possibility.
