CVE-2026-89478

CVE-2026-89478 is a use-after-free in the Linux kernel's SCTP implementation. An authenticated attacker can send an ASCONF DEL-IP to remove a transport while a DATA chunk is still in flight (on the socket backlog or direct path). The chunk's lingering transport reference causes the transport to b...
