CVE-2026-58087

The GETALL and SETALL commands in semctl2 recorded the number of semaphores in the target set, dropped the lock protecting the set, allocated a buffer sized for that count, and reacquired the lock. A sequence-number check was used to verify that the set had not been replaced in the interim, but t...

CVE-2026-58087

CVE-2026-58087 is a heap out-of-bounds access in the GETALL and SETALL commands of FreeBSD's semctl(2) system call. The root cause is a sequence-number wrap after 0x8000 create/destroy cycles: an unprivileged local user can rapidly destroy and recreate semaphore sets at the same index, causing a ...
