CVE-2023-53728

The CVE affects the Linux kernel’s posix-timers path, where posix_timer_add() allocates timer IDs by scanning from a cached, last-allocation ID. The loop that searches for a free ID is not properly synchronized with the starting value, because start is read locklessly while the hash lock is acqui...
