CVE-2026-53290

Low risk2th percentile — higher than 2% of all known CVEs
Summary
In the Linux kernel, a vulnerability in the DRM driver for Intel Xe GPUs was found where drm_dev_put() is called before the eustall stream is disabled and its resources freed. This can cause a use-after-free if the last device reference is dropped before cleanup operations complete.
Risk Assessment
The risk involves potential kernel memory corruption, which could lead to system crashes, data loss, or local privilege escalation.
Recommendation
Immediately update the Linux kernel to a version containing commit 35aff528f7297e949e5e19c9cd7fd748cf1cf21c or later, which moves drm_dev_put() after all device accesses are finished.
Original NVD description (English source)
In the Linux kernel, the following vulnerability has been resolved: drm/xe/eustall: Fix drm_dev_put called before stream disable in close In xe_eu_stall_stream_close(), drm_dev_put() is called before the stream is disabled and its resources are freed. If this drops the last reference, the device structures could be freed while the subsequent cleanup code still accesses them, leading to a use-after-free. Fix this by moving drm_dev_put() after all device accesses are complete. This matches the ordering in xe_oa_release(). (cherry picked from commit 35aff528f7297e949e5e19c9cd7fd748cf1cf21c)
