kernel: sctp: revalidate list cursor after sctp_sendmsg_to_asoc() in SCTP_SENDALL
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...

CVE-2026-53224
A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. Specifically, improper validation of embedded INIT chunk and address list lengths in SCTP cookies could allow a remote attacker to trigger out-of-bounds reads. This could lead to information disclosur...
PT-2026-52320
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the SCTP implementation where the sctp rcv asconf lookup function in net/sctp/input.c fails to properly validate the length of an ASCONF chunk. The function verifies i...
CVE-2026-52929
A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP stream handling. When an attempt to add outgoing streams is denied, the system fails to fully roll back the associated state. This incomplete rollback can leave behind stale stream metadata, which a subsequent stream...
CVE-2026-52924
A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. This vulnerability, a use-after-free, occurs when the system processes a Stale Cookie ERROR during the setup or reconfiguration of an SCTP association. A remote attacker could exploit this by sending...
EUVD-2026-38938
In the Linux kernel, the following vulnerability has been resolved: sctp: disable BH before calling udptunnelxmitskb udptunnelxmitskb / udptunnel6xmitskb are expected to run with BH disabled. After commit 6f1a9140ecda "add xmit recursion limit to tunnel xmit functions", on the path:...
Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1
In the Linux kernel, the following vulnerabilities have been resolved: sctp: Linearize cloned GSO packets in sctprcv. The cloned headskb still shares these frag SKBs in the fraglist with the original headskb. Accessing these frag SKBs is not safe. syzbot reported two bugs caused by the use of...
UBUNTU-CVE-2026-52917
In the Linux kernel, the following vulnerability has been resolved: sctp: diag: reject stale associations in dumpone path The SCTP exact sockdiag lookup can hold a transport reference, block on locksocksk, and then resume after sctpassociationfree has marked the association dead and freed its bin...
UBUNTU-CVE-2026-52924
In the Linux kernel, the following vulnerability has been resolved: sctp: purge outqueue on stale COOKIE-ECHO handling sctpstreamupdate is only invoked when the association is moved into COOKIEWAIT during association setup/reconfiguration. In this path, the outbound stream scheduler state...
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...
CVE-2026-52929
The CVE affects the Linux kernel SCTP stream handling. When ADD_OUT_STREAMS is denied, the rollback only shrinks queued chunks and lowers outcnt, leaving removed stream metadata behind. A subsequent re-add can reuse a stale ext and trigger a null-pointer dereference in the scheduler get path, pot...
