kernel: sctp: purge outqueue on stale COOKIE-ECHO handling

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...

UBUNTU-CVE-2026-72398

In the Linux kernel, the following vulnerability has been resolved: sctp: add INIT verification after cookie unpacking In SCTP handshake, the INIT chunk is initially processed by the server and embedded into the cookie carried in INIT-ACK. The client then returns this cookie via COOKIE-ECHO, wher...

CVE-2026-68300 sctp: auth: verify auth requirement when auth_chunk is NULL

In the Linux kernel, the following vulnerability has been resolved: sctp: auth: verify auth requirement when authchunk is NULL sctpauthchunkverify returns true unconditionally when chunk-authchunk is NULL, silently skipping authentication. This is incorrect when: 1. skbclone failed in the BH...

CVE-2026-68300

Summary: CVE-2026-68300 in the Linux kernel concerns SCTP authentication. The function sctp_auth_chunk_verify() incorrectly returns true when auth_chunk is NULL, allowing authentication to be bypassed under certain conditions (e.g., skb_clone() failure in BH path or absence of an AUTH before COOK...

CVE-2026-53246

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A remote attacker could exploit this by sending a specially crafted COOKIEECHO chunk to a listening SCTP server. The server's failure to properly validate the length of a cached peer INIT chunk within...
