CVE-2026-53290
HighCVSS 7.8Exploitation Probability (EPSS)
Low risk2th percentile — higher than 2% of all known CVEs
Summary
In the Linux kernel, a use-after-free vulnerability was found in the DRM driver for Intel Xe GPUs. The xe_eu_stall_stream_close() function called drm_dev_put() before disabling the stream and freeing resources, potentially accessing freed memory.
Risk Assessment
An attacker could exploit this vulnerability to gain unauthorized access to kernel memory, potentially leading to privilege escalation or information disclosure.
Recommendation
Immediately update the Linux kernel to a version containing commit 35aff528f7297e949e5e19c9cd7fd748cf1cf21c or later.
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)
