CVE-2026-80777

CVE-2026-80777 is a race condition in the Linux kernel's futex/pi subsystem. During exec() , there is a window between setting a task's futex exit state to OK and actually swapping its memory map (mm), during which the check comparing a waiter's mm against the owner's mm can return an incorrect r...

FreeBSD : FreeBSD -- hwpmc fails to detach PMCs during exec credential transitions (9c2801aa-a0fd-11f1-ae1f-bc241121aa0a)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 9c2801aa-a0fd-11f1-ae1f-bc241121aa0a advisory. When a process calls execve2 to execute a setuid or setgid image, hwpmc4 is supposed to detach PMCs own...

CVE-2025-40341 concerns a race in futex handling (robust_list) in the Linux kernel where sys_get_robust_list() and compat_get_robust_list() could leak a user process’s robust_list pointer across an exec() transition. The issue arises because ptrace_may_access() checks permissions before an exec()...

Kernel: sa_restorer information leak

The flushsignalhandlers function in kernel/signal.c in the Linux kernel before 3.8.4 preserves the value of the sarestorer field across an exec operation, which makes it easier for local users to bypass the ASLR protection mechanism via a crafted application containing a sigaction system call...
