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:...

CVE-2026-52929

The CVE-2026-52929 entry concerns the Linux kernel SCTP stream handling. When ADD_OUT_STREAMS is denied, the scheduler may leave removed stream metadata behind, enabling a later re-add to reuse a stale ext and trigger a null-pointer dereference in the scheduler get path. The fix tears down the re...

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...

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...

CVE-2026-9539

CVE-2026-9539 affects freedesktop.org libslirp (prior to v4.9.2) used on hypervisor host environments (e.g., QEMU). A vulnerability in the TCP urgent data handling (sosendoob) can cause an out-of-bounds heap read and integer underflow, enabling a privileged guest VM attacker (root or CAP_NET_RAW)...

CVE-2026-9539 libslirp TCP URG OOB Read Information Leak

An out-of-bounds heap read and integer underflow in the TCP urgent data handling sosendoob in freedesktop.org libslirp version before v4.9.2 on hypervisor host environments e.g., QEMU allows a privileged guest VM attacker root or CAPNETRAW to leak gigabytes of sensitive host-process heap memory v...

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...
