UBUNTU-CVE-2026-52929
In the Linux kernel, the following vulnerability has been resolved: sctp: stream: fully roll back denied add-stream state When ADDOUTSTREAMS is denied, SCTP only shrinks the queued chunks and then lowers outcnt. That leaves removed stream metadata behind, so a later re-add can reuse a stale ext a...
