kernel: futex/requeue: Prevent NULL pointer dereference in remove_waiter() on self-deadlock

A flaw was found in the Linux kernel's futex Fast Userspace Mutex requeue mechanism. When a non-top waiter attempts to requeue a Priority Inheritance PI futex it already owns, a NULL pointer dereference can occur. This issue, specifically within the removewaiter function during a self-deadlock...

kernel: rtmutex: Use waiter::task instead of current in remove_waiter()

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...

The remote RockyLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2026:38491 advisory. kernel: Linux kernel: Memory leak in networking due to incorrect GRO packet handling CVE-2026-22979 kernel: rtmutex: Use waiter::task instead of current...

The vulnerability of the futex_key_to_node_opt() function in the Linux operating system allows a hacker to trigger a service failure.

The vulnerability of the futexkeytonodeopt function in the Linux operating system’s kernel is related to the use of memory after it is freed. Exploiting this vulnerability could allow an attacker to cause a service failure...
