Overview

CVE-2024-44982 is a medium-severity vulnerability affecting linux linux_kernel. It was published on September 4, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

drm/msm/dpu: cleanup FB if dpu_format_populate_layout fails

If the dpu_format_populate_layout() fails, then FB is prepared, but not

cleaned up. This ends up leaking the pin_count on the GEM object and

causes a splat during DRM file closure:

msm_obj->pin_count
