AI-suggested
A patch is available and should be applied to affected Linux kernel versions. The fix involves updating to a kernel version where drm_dev_put() is correctly ordered after stream disable in xe_eu_stall_stream_close(). Users should consult their Linux distribution's security advisories and update accordingly. No additional mitigations are specified by the vendor advisory.
Description
A use-after-free vulnerability in the Linux kernel's drm/xe/eustall subsystem was fixed by correcting the order of resource cleanup in the xe_eu_stall_stream_close() function. The flaw involved calling drm_dev_put() before disabling the stream and freeing its resources, which could lead to device structures being freed prematurely while still accessed by cleanup code. This vulnerability is addressed by moving drm_dev_put() after all device accesses are complete. The issue affects multiple versions of the linux-hwe-edge kernel and has a CVSS score of 7.8.
