PT-2026-85599

In the Linux kernel, the following vulnerability has been resolved: futex: Avoid private hash use-after-free on final put futex private hash put drops the reference to fph before evaluating fph-mm for wake up var. futex ref put enables preemption again before returning. If that put drops the fina...

The vulnerability of the need_futex_hash_allocate_default() function in the kernel/fork.c module of the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the needfutexhashallocatedefault function in the kernel/fork.c module of the Linux operating system is related to the use of memory after it is freed. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility of the...

CVE-2026-80777: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: futex/pi: Plug private futex exec race The check for private futexes whether the waiter's mm, which is stored in the futexkey and copied into the pistate, is the same as the owner's mm is not sufficient for exec. exec has a gap...

PT-2026-85616

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A race condition exists during the initial allocation of mm-futex.phash.ref within the futex hash allocate function because it is performed without locking. This issue occurs during nest...

kernel: futex: Drop CLONE_THREAD requirement for private default hash alloc

A flaw was found in the Linux kernel's futex subsystem. The needfutexhashallocatedefault function incorrectly relies on CLONETHREAD semantics, which can lead to non-concurrency issues when memory allocations mm-futexref pcpu allocations are shared across CLONEVM clones, excluding vfork. This can...

SUSE CVE-2026-74658

In the Linux kernel, the following vulnerability has been resolved: futex: Prevent robust futex exit race some more A robust futex unlock stores 0 over the whole futex value - wiping FUTEXWAITERS - and wakes a single waiter. That wakeup is a one-shot notification: the protocol relies on its...

The vulnerability of the SYSCALL_DEFINE4() function in the kernel/futex/syscalls.c module of the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the SYSCALLDEFINE4 function in the kernel/futex/syscalls.c module of the Linux operating system is related to errors during the update of the reference counter. Exploiting this vulnerability can allow an attacker to compromise the confidentiality, integrity, and accessibility...

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...
