conditions.\nPR:N - Dynamic demo-mode node ACL generation is enabled by default, and even a login-only session can submit an unmapped-LUN command that queues a CHECK CONDITION CTIO without target credentials.\nUI:N - After the target is configured and active, malicious fabric traffic alone reaches the vulnerable abort path without victim action.\nS:U - The vulnerable qla2xxx driver and the affected kernel resources share the same security authority; kernel compromise does not itself cross a CVSS scope boundary.\nC:H - The TYPE_TGT_CMD-to-SRB confusion makes sp->done alias se_cmd.priv; with a pSCSI backend this can target request memory containing attacker-controlled CDB data, making kernel control-flow hijacking and arbitrary memory disclosure defensible.\nI:H - The attacker-influenced indirect call through backend-private command memory can potentially provide kernel code execution and arbitrary modification, rather than being limited to the observed NULL call.\nA:H - The demonstrated result is an invalid supervisor instruction fetch and kernel oops, and repeatable fabric traffic can crash or continually reset the storage target." } ] } ], "affected":
