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...

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...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: SCTP: Set skstate back to CLOSED if autobind fails in sctplistenstart. In sctplistenstart called by sctpinetlisten, it should set skstate back to CLOSED if sctpautobind fails for any reason. Otherwise, the next time...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.10, and Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: SCTP: Initialization of additional fields in sctpv6fromsk was incorrect, leading to undefined behavior. SYZbot discovered that sin6scopeid was not properly initialized, causing undefined behavior. sin6scopeid and sin6flowinfo...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: SCTP: Fixed a memory leak in sctpstreamoutqmigrate. When sctpstreamoutqmigrate is called to release resources related to streamouts, the memory pointed to by priohead in the streamout context is not released properly. The details...

CVE-2026-49759

A flaw was found in Erlang OTP Open Telecom Platform erts, specifically within the inetdrv component. An unauthenticated remote attacker can exploit a stack-based buffer overflow vulnerability by sending a specially crafted Stream Control Transmission Protocol SCTP ERROR chunk. This can lead to a...

CVE-2026-46340 Netty: SCTP reassembly nests buffers without bound

Netty is a network application framework for development of protocol servers and clients. In versions of netty-transport-sctp prior to 4.1.135.Final and 4.2.15.Final, for each non-complete SctpMessage fragment the handler does fragments.putstreamId, Unpooled.wrappedBufferfrag, byteBuf, wrapping t...

CVE-2026-46340

Netty SCTP reassembly vulnerability (CVE-2026-46340) affects netty-transport-sctp before 4.1.135.Final and 4.2.15.Final. For each non-complete SctpMessage fragment, fragments are accumulated by wrapping the previous accumulator with the new slice into a new CompositeByteBuf, creating an unbounded...

CVE-2026-37220

FlexRIC v2.0.0 crashes when an SCTP association is closed before an E2SETUPREQUEST is sent. The near-RT RIC assumes a mapping between SCTP association and E2 node always exists in the cleanup path and enforces this via assert. A remote unauthenticated attacker can crash the near-RT RIC port 36421...
