CVE-2026-89479

CVE-2026-89479 is a use-after-free in the Linux kernel's SCTP implementation. In sctp_endpoint_bh_rcv(), the association is cached in chunk->asoc and chunk->transport without holding a reference. A remote peer can bundle COOKIE ECHO, SHUTDOWN, and SHUTDOWN ACK in a single packet: the COOKIE...

CVE-2026-89478 sctp: drop a chunk if its transport was removed

In the Linux kernel, the following vulnerability has been resolved: sctp: drop a chunk if its transport was removed sctprcv resolves the transport once per packet and leaves it in chunk-transport. The lookup reference, or the one sctpaddbacklog takes if the socket is owned by userspace, keeps it...

kernel: sctp: fix race between sctp_wait_for_connect and peeloff

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A race condition exists in the sctpwaitforconnect function, where a socket lock is temporarily released and re-acquired. During this brief period, another process can move the SCTP association to a...

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A race condition exists in the SCTPSENDALL path where a cached list entry is not properly revalidated after the socket lock is temporarily released. This allows a local attacker or a remote attacker v...

CVE-2026-74688

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. This vulnerability arises when the sctpmakeheartbeatack function caches a destination transport without taking a proper reference. If the associated peer transport is removed while a HEARTBEAT ACK chu...

CVE-2026-74586 sctp: clear new_transport when removing a peer

In the Linux kernel, the following vulnerability has been resolved: sctp: clear newtransport when removing a peer sctpprocessasconfparam stores a newly added peer transport in asoc-newtransport. After all parameters in the ASCONF chunk have been processed, sctpsfdoasconf uses this pointer to send...
