CVE-2026-4878 Libcap: libcap: privilege escalation via toctou race condition in cap_set_file()

A flaw was found in libcap. A local unprivileged user can exploit a Time-of-check-to-time-of-use TOCTOU race condition in the capsetfile function. This allows an attacker with write access to a parent directory to redirect file capability updates to an attacker-controlled file. By doing so,...

GO-2026-4864 TOCTOU permits root escape on Linux via Root.Chmod in os in internal/syscall/unix

On Linux, if the target of Root.Chmod is replaced with a symlink while the chmod operation is in progress, Chmod can operate on the target of the symlink, even when the target lies outside the root. The Linux fchmodat syscall silently ignores the ATSYMLINKNOFOLLOW flag, which Root.Chmod uses to...
