CVE-2026-4878 (GCVE-0-2026-4878)
Vulnerability from cvelistv5 – Published: 2026-04-09 14:49 – Updated: 2026-05-04 01:50
VLAI?
Title
Libcap: libcap: privilege escalation via toctou race condition in cap_set_file()
Summary
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.
