What the advisory describes
In the Linux kernel, the following vulnerability has been resolved: drm/xe/oa: Fix exec_queue leak on width check in stream open In xe_oa_stream_open_ioctl(), when param.exec_q->width > 1 the function returns -EOPNOTSUPP directly, skipping the existing err_exec_q cleanup path. The exec_queue reference obtained by xe_exec_queue_lookup() is leaked. The exec queue holds a reference on the xe_file, which is only dropped during queue teardown. The leaked lookup ref is not on the file's exec_queue xarray, so file close cannot release it. This keeps both the exec queue and the file private state pinned indefinitely. Jump to err_exec_q instead of returning directly so the reference is released. (cherry picked from commit 339fa0be9e4a5d69fa47e91f4a36574224fb478f)
