Linux Linux, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 6 취약점
In the Linux kernel, the following vulnerability has been resolved: IB/isert: Reject login PDUs shorter than ISER_HEADERS_LEN In drivers/infiniband/ulp/isert/ib_isert.c, isert_login_recv_done() computes the login request payload length as wc->byte_len minus ISER_HEADERS_LEN with no lower bound, and login_req_len is a signed int. A remote iSER initiator can post a login Send work request carrying fewer than ISER_HEADERS_LEN (76) bytes, so the subtraction underflows and login_req_len becomes negative. isert_rx_login_req() then reads that negative length back into a signed int, takes size = mi...

조치방안
제3자 참조와 수정 버전 값(5.10.259, 5.15.210, 6.1.176, 6.6.143, 6.12.94, 6.18.36, 7.0.13)은 보조 근거로만 사용하고, 공급사 공식 보안 권고에서 조치 기준을 재확인합니다.
조치 후 확인사항
패치 후 같은 명령으로 전체 버전을 다시 확인해 Linux Linux, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 6 5.10.259, 5.15.210, 6.1.176, 6.6.143, 6.12.94, 6.18.36, 7.0.13 기준을 충족하는지 확인합니다. 이어서 유형 미확정 관련 오류·공격 흔적이 새로 발생하지 않는지 확인합니다.
