Description

Updated libcap packages fix security vulnerabilities

CVE-2026-4878. 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.
