UBUNTU-CVE-2026-53176

In the Linux kernel, the following vulnerability has been resolved: IB/isert: Reject login PDUs shorter than ISERHEADERSLEN In drivers/infiniband/ulp/isert/ibisert.c, isertloginrecvdone computes the login request payload length as wc-bytelen minus ISERHEADERSLEN with no lower bound, and loginreql...

CVE-2026-53176

CVE-2026-53176 affects the Linux kernel iSER (IB/isert) login handling in ib_isert.c. A remote iSER initiator could send a login PDU shorter than ISER_HEADERS_LEN (76), causing an integer underflow in isert_login_recv_done() when computing login_req_len, leading to a negative length used in a mem...
