High [CVE-2026-76235] unauthenticated remote memory leak via CockpitLang cookie in send_login_html
CVE-2026-76235Source published Source updated
A memory leak flaw was found in cockpit-ws. The login page handler leaks a heap allocation on every unauthenticated request that carries a CockpitLang cookie, allowing a remote unauthenticated attacker to exhaust memory on the host and cause a denial of service. Red Hat rates this issue as Moderate impact. Although cockpit-ws is reachable by an unauthenticated remote client and the resulting memory exhaustion can be sustained indefinitely, cockpit-ws is a stateless web console component: its crash or restart does not itself compromise the confidentiality or integrity of the host or of other running services, and the process is automatically restarted by systemd. Red Hat severity: Moderate — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-401. Affected Red Hat…
