  • CVE-2026-4878

Summary
libcap security update
Details

This is a library for getting and setting POSIX.1e (formerly POSIX 6) draft 15 capabilities.

Security Fix(es):

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 cap_set_file() 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, capabilities can be injected into or stripped from unintended executables, leading to privilege escalation.(CVE-2026-4878)
