CVE-2026-74688

A use-after-free vulnerability in the Linux kernel's SCTP implementation. The function sctp_make_heartbeat_ack() caches a destination transport pointer without taking a reference. When src_out_of_asoc_ok is enabled, a HEARTBEAT ACK may remain queued on control_chunk_list. If the peer transport is...
