Description
A flaw was found in the Linux kernel's drm/xe/eustall component. This vulnerability occurs because the drm_dev_put() function is called before a stream is disabled and its resources are freed within xe_eu_stall_stream_close(). This timing issue can lead to a use-after-free condition, where device structures might be accessed after they have been deallocated. A local attacker could potentially exploit this to cause system instability or a denial of service (DoS).
