CVE-2026-68320

CVE-2026-68320 concerns the Linux kernel SCTP implementation. The issue arises in sctp_auth_ep_add_chunkid, which uses SCTP_NUM_CHUNK_TYPES (20) as the capacity limit for ep->auth_chunk_list, while the destination in sctp_cookie/gathered state only holds SCTP_AUTH_MAX_CHUNKS (16) entries. When...

CVE-2026-68315

Summary (CVE-2026-68315) : In the Linux kernel SCTP implementation, processing a RESET_IN_REQUEST from a peer can derive a stream count from the parameter length and then exceed SCTP_MAX_CHUNK_LEN when constructing the corresponding RESET_OUT_REQUEST. The OUT header is 16 bytes vs IN header 8 byt...

CVE-2026-68162

CVE-2026-68162 is a Linux kernel SCTP vulnerability (local) where a Use-After-Free can occur during netns teardown due to an auth_enable sysctl window. The bug stems from SCTP’s per-net sysctl state being registered before the control socket is fully established and remaining writable after inet_...
