CVE-2026-52976 is a memory-safety vulnerability in the Linux kernel DRM/Xe subsystem's xe_exec_queue_create_ioctl() function. Two incorrect error-cleanup paths free execution queues without first removing their list references. If xe_hw_engine_group_add_exec_queue() fails while the VM uses preempt fence mode, cleanup skips xe_exec_queue_kill(), leaving a dangling pointer in the VM's compute execution queue list. If xa_alloc() fails after hardware engine group registration succeeds, cleanup omits xe_hw_engine_group_del_exec_queue(), freeing a queue that remains linked into the hardware engine group and causing a use-after-free.
