A use-after-free (UAF) vulnerability in the Linux kernel's drm/xe/dma-buf subsystem was fixed. The issue involved a retry loop that did not work correctly because a buffer object (bo) would be freed on error, leading to a UAF condition. The fix involved changing the allocation and initialization sequence to make the retry safe. This vulnerability is tracked as CVE-2026-52950 and affects multiple versions of the linux-hwe-edge kernel prior to 7.0.0-28.28 and related versions. The vulnerability has a CVSS score of 7.8, indicating high impact on confidentiality, integrity, and availability. A patch is available and included in updated kernel packages. Users should update and reboot to apply the fix. Join the discussion | GCVE Database | 06/24/2026, 17:17:00 UTC Added: 07/17/2026, 10:18:19 UTC |
