SUSE CVE-2026-43499

In the Linux kernel, the following vulnerability has been resolved: rtmutex: Use waiter::task instead of current in removewaiter removewaiter is used by the slowlock paths, but it is also used for proxy-lock rollback in rtmutexstartproxylock when invoked from futexrequeue. In the latter case...

CVE-2026-43499

A flaw was found in the Linux kernel. When the kernel's real-time mutex rtmutex component performs a specific operation called 'proxy-lock rollback' during futex requeue, it incorrectly handles task pointers. This can lead to a 'Use-After-Free' UAF vulnerability, where the system attempts to use...

CVE-2026-43499

The CVE-2026-43499 issue concerns the Linux kernel rtmutex path where remove_waiter() operated on current during dequeue in rt_mutex_start_proxy_lock() via futex_requeue(). This caused: (1) rbtree dequeue without waiter::task::pi_lock, (2) waiter task pi_blocked_on not cleared (dangling pointer, ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: futex: It is required that sysfutexrequeue has identical flags. Nicholas reported that his LLM found it possible to create a UaF when sysfutexrequeue is used with different flags. The initial motivation for allowing different fla...

In the Linux kernel, the following vulnerability has been resolved: futex: Require sysfutexrequeue to have identical flags Nicholas reported that his LLM found it was possible to create a UaF when sysfutexrequeue is used with different flags. The initial motivation for allowing different flags wa...

CVE-2026-31554

A flaw was found in the Linux kernel. A local attacker could exploit a use-after-free vulnerability by calling the sysfutexrequeue function with inconsistent flags. This could lead to a system crash, resulting in a denial of service, or potentially allow for privilege escalation...

CVE-2026-31554

The CVE-2026-31554 entry concerns a Linux kernel futex requeue issue: using sys_futex_requeue() with different flags could enable a use-after-free/UaF condition. To fix, the code now requires identical flags for sys_futex_requeue() (matching the behavior of old-style sys_futex() requeue). The vul...

kernel: Linux kernel: Denial of Service via unsafe requeue in rxrpc_recvmsg

A flaw was found in the Linux kernel. A local unprivileged process can exploit an unsafe requeue path in the rxrpcrecvmsg function by using AFRXRPC sockets with MSGDONTWAIT and MSGPEEK flags. This improper handling of the receive message queue can lead to memory corruption, such as Use-After-Free...
