CVE-2026-68376 sctp: fix auth_hmacs array size in struct sctp_cookie

In the Linux kernel, the following vulnerability has been resolved: sctp: fix authhmacs array size in struct sctpcookie The authhmacs array in struct sctpcookie is supposed to store a complete SCTPAUTHHMACALGO parameter, which consists of a struct sctpparamhdr followed by N HMAC identifiers...

CVE-2026-68376

CVE-2026-68376 involves the Linux kernel SCTP implementation. The bug is in the auth_hmacs array within struct sctp_cookie: its size was computed using an extra 2 bytes instead of the full SCTP parameter header size, which is sizeof(struct sctp_paramhdr) = 4 bytes. When four HMAC identifiers are ...

CVE-2026-53224

The vulnerability CVE-2026-53224 affects the Linux kernel SCTP implementation. The issue arises from insufficient validation of embedded INIT chunks and address list lengths in cookies: sctp_unpack_cookie() may accept a truncated INIT chunk, and the subsequent sctp_process_init() could read INIT ...
