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...

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...

CVE-2026-74587
A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. During peer restart handling, the system improperly releases a cached ASCONF chunk without clearing its pointer, leading to a use-after-free vulnerability. A remote attacker could exploit this by...
CVE-2026-74586
A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. An authenticated remote SCTP peer can trigger a use-after-free vulnerability by adding and then immediately removing a transport within the same ASCONF chunk. This can lead to a system crash, resultin...
