CVE-2026-91203 — MEDIUM (6.0)

Vulnerability Description

A flaw was found in cockpit-files. This vulnerability allows a local attacker to exploit a timing issue, known as a symlink race condition, during privileged file operations such as changing file ownership or permissions. By manipulating directory entries and winning this race, the attacker can redirect these operations to unintended files. This could lead to unauthorized changes in file ownership and permissions on arbitrary files, potentially compromising system integrity and availability by altering system or application states or rendering services unusable.
