kernel: sctp: validate cached peer INIT chunk length in COOKIE_ECHO processing

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A remote attacker could exploit this by sending a specially crafted COOKIEECHO chunk to a listening SCTP server. The server's failure to properly validate the length of a cached peer INIT chunk within...

CVE-2026-74752: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: sctp: validate cookie AUTH state before use When cookie authentication is disabled, COOKIEECHO restores fixed-size AUTH fields directly from peer-controlled cookie bytes. A forged RANDOM length, HMAC list, or CHUNKS list can then...

Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability. This vulnerability stems from SCTP’s handling of COOKIEECHO, where it does not verify the RANDOM, HMAC, and CHUNKS parameters of the cookie. Forgeries of these parameters can lead to out-of-bounds reads and writes, potentially allowing for local...
