In the Linux kernel, the following vulnerability has been resolved: sctp: fix errchunk memory leaks in INIT handling When sctpverifyinit encounters unrecognized parameters, it allocates an errchunk to report them. However, this chunk is leaked in several code paths: 1. In sctpsfdo51Binit, if...

CVE-2026-72413

The CVE-2026-72413 entry describes a Linux kernel SCTP issue where an err_chunk allocated during INIT handling in sctp_verify_init() could leak in multiple code paths (INIT handling in sctp_sf_do_5_1B_init and sctp_sf_do_unexpected_init, including the success path). The workaround/mitigation is t...

CVE-2026-72413 sctp: fix err_chunk memory leaks in INIT handling

In the Linux kernel, the following vulnerability has been resolved: sctp: fix errchunk memory leaks in INIT handling When sctpverifyinit encounters unrecognized parameters, it allocates an errchunk to report them. However, this chunk is leaked in several code paths: 1. In sctpsfdo51Binit, if...

CVE-2026-72398

CVE-2026-72398 concerns the Linux kernel SCTP implementation. When cookie authentication is disabled, an INIT reconstructed during COOKIE-ECHO could be untrusted unless explicitly re-verified; the patch adds sctp_verify_init() checks after cookie unpacking in COOKIE-ECHO paths and tightens sctp_u...

CVE-2026-72398 sctp: add INIT verification after cookie unpacking

In the Linux kernel, the following vulnerability has been resolved: sctp: add INIT verification after cookie unpacking In SCTP handshake, the INIT chunk is initially processed by the server and embedded into the cookie carried in INIT-ACK. The client then returns this cookie via COOKIE-ECHO, wher...

CVE-2026-72383

In the Linux kernel SCTP subsystem, CVE-2026-72383 describes a race in sctp_free_addr_wq() where addr_wq_timer could be re-entered after addr_wq_lock is held, allowing a sctp_addr_wq_timeout_handler() to access freed memory (use-after-free). The vulnerability is mitigated by calling timer_shutdow...

CVE-2026-72021

Summary: The CVE-2026-72021 issue affects the Linux kernel’s IPVS SCTP state lookup. The kernel incorrectly read the SCTP chunk header using a wrong offset for IPv6 when extension headers were present, causing misclassification of handshake steps (e.g., INIT1 vs ESTABLISHED) and incorrect managem...
