Vulnerability description

DayBreach CVE AI Research

CVE-2026-4878 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.

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.
