The callers check only IS_ERR() on the\nreturn value; since IS_ERR(NULL) == false the check passes, and\nsuspend_queues() calls q_array_invalidate() which immediately\ndereferences NULL while iterating num_queues times.\n\nUserspace can trigger this via kfd_ioctl_set_debug_trap() by supplying\nnum_queues > 0 with a zero queue_array_ptr, causing a kernel panic.\n\nA NULL usr_queue_id_array with num_queues == 0 is a legitimate no-op\n(q_array_invalidate never executes, and resume_queues already guards\nall queue_ids dereferences behind a NULL check). Return ERR_PTR(-EINVAL)\nonly when num_queues is non-zero and the pointer is absent; both callers\nalready propagate IS_ERR() returns correctly to userspace.\n\n(cherry picked from commit f165a82cdf503884bb1797771c61b2fcc72113d4)\n\n## Affected\n\n- `Linux >= a70a93fa568b4f05aba548dadb673703eccf5480 < 62bd09e23a23da70f9aae02748eba3e6bd93095d`\n- `Linux >= a70a93fa568b4f05aba548dadb673703eccf5480 < daeceb0fe2a19651c58bbfa3d9d515ecb6ca8996`\n- `Linux >= a70a93fa568b4f05aba548dadb673703eccf5480 < 72e259a32084c42816152c346096d2edd4213e23`\n- `Linux >= a70a93fa568b4f05aba548dadb673703eccf5480 < e1965e8913cfbf17622ca12638e7a07f68ba0848`\n- `Linux >= a70a93fa568b4f05aba548dadb673703eccf5480 < 2bd550b547deabef98bd3b017ff743b7c34d3a6d`\n- `Linux 6.5`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
