SUSE CVE-2026-46227

In the Linux kernel, the following vulnerability has been resolved: sctp: revalidate list cursor after sctpsendmsgtoasoc in SCTPSENDALL The SCTPSENDALL path in sctpsendmsg iterates ep-asocs with listforeachentrysafe, which caches the next entry in @tmp before the loop body runs. The body calls...

CVE-2026-46227

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...
