[PATCH OLK-5.10] nvme-tcp: fix potential memory corruption in nvme_tcp_recv_pdu()

From: Maurizio Lombardi <mlombard(a)redhat.com> mainline inclusion from mainline-v6.14 commit ad95bab0cd28ed77c2c0d0b6e76e03e031391064 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBY43W CVE: CVE-2025-21927 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- nvme_tcp_recv_pdu() doesn't check the validity of the header length. When header digests are enabled, a target might send a packet with an invalid header length (e.g. 255), causing nvme_tcp_verify_hdgst() to access memory outside the allocated area and cause memory corruptions by overwriting it with the calculated digest.
