This defeats the bounds guards in posix_info_sid_size(),allowing out-of-bounds reads into adjacent kernel memory.\nFix this by rejecting responses where the calculated sidsbuf_end wouldexceed the received iov boundaries or cause pointer wraparound.\nhttps://www.cve.org/CVERecord?id=CVE-2026-98405https://git.kernel.org/stable/c/d91b9a3b2b38e5ac1b51e9e5b23fe53ad7b49644https://git.kernel.org/stable/c/b862996e5105be1293da9cdc85da77b76021c3bdhttps://git.kernel.org/stable/c/2f8ed71aaaba3bc8b19cd9930cc62e63e142b299https://git.kernel.org/stable/c/eac6917a42899aad0617bbf04798c5dd946a1fe5https://git.kernel.org/stable/c/b09d092eb24ad0110f16a9b7c1ed5d2a0c1733dc#kernel #Linux#CVE_2026_98405#bot", "creation_timestamp": "2026-10-14T18:35:31.707941Z"}]}
