CVE-2026-52924

A flaw was found in the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation. This vulnerability, a use-after-free, occurs when the system processes a Stale Cookie ERROR during the setup or reconfiguration of an SCTP association. A remote attacker could exploit this by sending specially crafted SCTP packets. This could lead to a system crash, causing a Denial of Service (DoS).
