  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdkfd: fix NULL dereference in get_queue_ids()\n\nWhen usr_queue_id_array is NULL and num_queues is non-zero,\nget_queue_ids() returns NULL. 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 \u003e 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)",
