kernel: posix-cpu-timers: Prevent UAF caused by non-leader exec() race

A flaw was found in the Linux kernel's CPU timer functionality. A race condition, which is a timing issue between different operations, can occur when a process attempts to delete a timer while another operation is still trying to access it. This can lead to a Use-After-Free UAF vulnerability,...

CVE-2026-72068

CVE-2026-72068 affects the Linux kernel’s posix-cpu-timers, specifically the update_rlimit_cpu() path. On 32‑bit kernels, rlim_new * NSEC_PER_SEC is computed in 32-bit space, causing truncation when rlim_new > 4 seconds and leading to an incorrect (too small) nsecs value stored in the CPU time...
