AI-suggested

An official patch is available and should be applied by updating to the fixed Linux kernel versions as provided by the vendor. After applying the update, a system reboot is required. The vendor advisory confirms the fix and recommends recompiling third-party kernel modules due to ABI changes. No additional mitigation steps are necessary beyond applying the official update.

Description

A memory leak vulnerability in the Linux kernel's drm/xe subsystem was fixed. The flaw involved a failure to free a pre-allocated buffer object (bo) on allocation failure in xe_dma_buf_init_obj(), potentially leading to resource leaks. The fix ensures proper freeing of the buffer object on error paths to prevent leaks. This issue affects multiple Linux kernel versions prior to 7.0.0-28.28 and related builds. The vulnerability has a medium severity with a CVSS score of 5.5 and does not impact confidentiality or integrity but affects availability. A patch is available and should be applied to affected systems.
