| CVE-2026-23357 | 1 Linux | 1 Linux Kernel | 2026-04-24 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: can: mcp251x: fix deadlock in error path of mcp251x_open The mcp251x_open() function call free_irq() in its error path with the mpc_lock mutex held. But if an interrupt already occurred the interrupt handler will be waiting for the mpc_lock and free_irq() will deadlock waiting for the handler to finish. This issue is similar to the one fixed in commit 7dd9c26bd6cf ("can: mcp251x: fix deadlock if an interrupt occurs during mcp251x_open") but for the error path. To solve this issue move the call to free_irq() after the lock is released. Setting `priv->force_quit = 1` beforehand ensure that the IRQ handler will exit right away once it acquired the lock. | ||||

[ 1362.191101] [<806c2640>] register_netdevice_notifier+0x60/0x168 <-- Trying to get lock "rtnl_mutex" via rtnl_lock(); [ 1362.197073] [<805504ac>] netdev_trig_activate+0x194/0x1e4 [ 1362.202490] [<8054e28c>] led_trigger_set+0x1d4/0x360 <-- Hold lock "triggers_list_lock" by down_read(&triggers_list_lock); [ 1362.207511] [<8054eb38>] led_trigger_write+0xd8/0x14c [ 1362.212566] [<80381d98>] sysfs_kf_bin_write+0x80/0xbc [ 1362.217688] [<8037fcd8>] kernfs_fop_write_iter+0x17c/0x28c [ 1362.223174] [<802cbd70>] vfs_write+0x21c/0x3c4 [ 1362.227712] [<802cc0c4>] ksys_write+0x78/0x12c [ 1362.232164] [<80014504>] syscall_common+0x34/0x58 Here LEDS_TRIGGER_NETDEV is being enabled on an LED. It first takes triggers_list_lock and then RTNL. A classical AB-BA deadlock. phy_led_triggers_registers() does not require the RTNL, it does not make any calls into the network stack which require protection. There is also no requirement the PHY has been attached to a MAC, the triggers only make use of phydev state. This allows the call to phy_led_triggers_registers() to be placed elsewhere. PHY probe() and release() don't hold RTNL, so solving the AB-BA deadlock. | ||||
| CVE-2026-23362 | 1 Linux | 1 Linux Kernel | 2026-04-24 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: can: bcm: fix locking for bcm_op runtime updates Commit c2aba69d0c36 ("can: bcm: add locking for bcm_op runtime updates") added a locking for some variables that can be modified at runtime when updating the sending bcm_op with a new TX_SETUP command in bcm_tx_setup(). Usually the RX_SETUP only handles and filters incoming traffic with one exception: When the RX_RTR_FRAME flag is set a predefined CAN frame is sent when a specific RTR frame is received. Therefore the rx bcm_op uses bcm_can_tx() which uses the bcm_tx_lock that was only initialized in bcm_tx_setup(). Add the missing spin_lock_init() when allocating the bcm_op in bcm_rx_setup() to handle the RTR case properly. | ||||
| CVE-2026-23420 | 1 Linux | 1 Linux Kernel | 2026-04-24 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: wifi: wlcore: Fix a locking bug Make sure that wl->mutex is locked before it is unlocked. This has been detected by the Clang thread-safety analyzer. | ||||
| CVE-2026-23400 | 1 Linux | 1 Linux Kernel | 2026-04-24 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: rust_binder: call set_notification_done() without proc lock Consider the following sequence of events on a death listener: 1. The remote process dies and sends a BR_DEAD_BINDER message. 2. The local process invokes the BC_CLEAR_DEATH_NOTIFICATION command. 3. The local process then invokes the BC_DEAD_BINDER_DONE. Then, the kernel will reply to the BC_DEAD_BINDER_DONE command with a BR_CLEAR_DEATH_NOTIFICATION_DONE reply using push_work_if_looper(). However, this can result in a deadlock if the current thread is not a looper. This is because dead_binder_done() still holds the proc lock during set_notification_done(), which called push_work_if_looper(). Normally, push_work_if_looper() takes the thread lock, which is fine to take under the proc lock. But if the current thread is not a looper, then it falls back to delivering the reply to the process work queue, which involves taking the proc lock. Since the proc lock is already held, this is a deadlock. Fix this by releasing the proc lock during set_notification_done(). It was not intentional that it was held during that function to begin with. I don't think this ever happens in Android because BC_DEAD_BINDER_DONE is only invoked in response to BR_DEAD_BINDER messages, and the kernel always delivers BR_DEAD_BINDER to a looper. So there's no scenario where Android userspace will call BC_DEAD_BINDER_DONE on a non-looper thread. | ||||

| CVE-2009-1961 | 6 Canonical, Debian, Linux and 3 more | 8 Ubuntu Linux, Debian Linux, Linux Kernel and 5 more | 2026-04-23 | 4.7 Medium |
| The inode double locking code in fs/ocfs2/file.c in the Linux kernel 2.6.30 before 2.6.30-rc3, 2.6.27 before 2.6.27.24, 2.6.29 before 2.6.29.4, and possibly other versions down to 2.6.19 allows local users to cause a denial of service (prevention of file creation and removal) via a series of splice system calls that trigger a deadlock between the generic_file_splice_write, splice_from_pipe, and ocfs2_file_splice_write functions. | ||||
| CVE-2009-0935 | 1 Linux | 1 Linux Kernel | 2026-04-23 | 5.5 Medium |
| The inotify_read function in the Linux kernel 2.6.27 to 2.6.27.13, 2.6.28 to 2.6.28.2, and 2.6.29-rc3 allows local users to cause a denial of service (OOPS) via a read with an invalid address to an inotify instance, which causes the device's event list mutex to be unlocked twice and prevents proper synchronization of a data structure for the inotify instance. | ||||
| CVE-2009-1243 | 1 Linux | 1 Linux Kernel | 2026-04-23 | 5.5 Medium |
| net/ipv4/udp.c in the Linux kernel before 2.6.29.1 performs an unlocking step in certain incorrect circumstances, which allows local users to cause a denial of service (panic) by reading zero bytes from the /proc/net/udp file and unspecified other files, related to the "udp seq_file infrastructure." | ||||
| CVE-2009-1388 | 2 Linux, Redhat | 3 Linux Kernel, Enterprise Linux, Rhel Eus | 2026-04-23 | 5.5 Medium |
| The ptrace_start function in kernel/ptrace.c in the Linux kernel 2.6.18 does not properly handle simultaneous execution of the do_coredump function, which allows local users to cause a denial of service (deadlock) via vectors involving the ptrace system call and a coredumping thread. | ||||
| CVE-2008-4302 | 3 Debian, Linux, Redhat | 3 Debian Linux, Linux Kernel, Enterprise Linux | 2026-04-23 | 5.5 Medium |
| fs/splice.c in the splice subsystem in the Linux kernel before 2.6.22.2 does not properly handle a failure of the add_to_page_cache_lru function, and subsequently attempts to unlock a page that was not locked, which allows local users to cause a denial of service (kernel BUG and system crash), as demonstrated by the fio I/O tool. | ||||
| CVE-2009-2699 | 1 Apache | 2 Http Server, Portable Runtime | 2026-04-23 | 7.5 High |
| The Solaris pollset feature in the Event Port backend in poll/unix/port.c in the Apache Portable Runtime (APR) library before 1.3.9, as used in the Apache HTTP Server before 2.2.14 and other products, does not properly handle errors, which allows remote attackers to cause a denial of service (daemon hang) via unspecified HTTP requests, related to the prefork and event MPMs. | ||||
| CVE-2006-5158 | 3 Canonical, Linux, Redhat | 7 Ubuntu Linux, Linux Kernel, Enterprise Linux and 4 more | 2026-04-23 | 7.5 High |
| The nlmclnt_mark_reclaim in clntlock.c in NFS lockd in Linux kernel before 2.6.16 allows remote attackers to cause a denial of service (process crash) and deny access to NFS exports via unspecified vectors that trigger a kernel oops (null dereference) and a deadlock. | ||||
| CVE-2006-4342 | 1 Redhat | 1 Enterprise Linux | 2026-04-23 | 5.5 Medium |
| The kernel in Red Hat Enterprise Linux 3, when running on SMP systems, allows local users to cause a denial of service (deadlock) by running the shmat function on an shm at the same time that shmctl is removing that shm (IPC_RMID), which prevents a spinlock from being unlocked. | ||||
| CVE-2009-2857 | 1 Oracle | 2 Opensolaris, Solaris | 2026-04-23 | 5.5 Medium |
| The kernel in Sun Solaris 8, 9, and 10, and OpenSolaris before snv_103, does not properly handle interaction between the filesystem and virtual-memory implementations, which allows local users to cause a denial of service (deadlock and system halt) via vectors involving mmap and write operations on the same file. | ||||
| CVE-2025-43510 | 1 Apple | 11 Ios, Ipad Os, Ipados and 8 more | 2026-04-22 | 7.8 High |

This issue is fixed in iOS 18.7.2 and iPadOS 18.7.2, iOS 26.1 and iPadOS 26.1, macOS Sequoia 15.7.2, macOS Sonoma 14.8.2, macOS Tahoe 26.1, tvOS 26.1, visionOS 26.1, watchOS 26.1. A malicious application may cause unexpected changes in memory shared between processes. | ||||
| CVE-2025-38436 | 1 Linux | 1 Linux Kernel | 2026-04-20 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/scheduler: signal scheduled fence when kill job When an entity from application B is killed, drm_sched_entity_kill() removes all jobs belonging to that entity through drm_sched_entity_kill_jobs_work(). If application A's job depends on a scheduled fence from application B's job, and that fence is not properly signaled during the killing process, application A's dependency cannot be cleared. This leads to application A hanging indefinitely while waiting for a dependency that will never be resolved. Fix this issue by ensuring that scheduled fences are properly signaled when an entity is killed, allowing dependent applications to continue execution. | ||||
| CVE-2026-23130 | 1 Linux | 1 Linux Kernel | 2026-04-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix dead lock while flushing management frames Commit [1] converted the management transmission work item into a wiphy work. Since a wiphy work can only run under wiphy lock protection, a race condition happens in below scenario: 1. a management frame is queued for transmission. 2. ath12k_mac_op_flush() gets called to flush pending frames associated with the hardware (i.e, vif being NULL). Then in ath12k_mac_flush() the process waits for the transmission done. 3. Since wiphy lock has been taken by the flush process, the transmission work item has no chance to run, hence the dead lock. >From user view, this dead lock results in below issue: wlp8s0: authenticate with xxxxxx (local address=xxxxxx) wlp8s0: send auth to xxxxxx (try 1/3) wlp8s0: authenticate with xxxxxx (local address=xxxxxx) wlp8s0: send auth to xxxxxx (try 1/3) wlp8s0: authenticated wlp8s0: associate with xxxxxx (try 1/3) wlp8s0: aborting association with xxxxxx by local choice (Reason: 3=DEAUTH_LEAVING) ath12k_pci 0000:08:00.0: failed to flush mgmt transmit queue, mgmt pkts pending 1 The dead lock can be avoided by invoking wiphy_work_flush() to proactively run the queued work item. Note actually it is already present in ath12k_mac_op_flush(), however it does not protect the case where vif being NULL. Hence move it ahead to cover this case as well. Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00302-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.115823.3 | ||||
