CVE-2023-53002

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A memory leak issue has been identified in the Linux kernel, specifically in the drm/i915 component. The problem arises from the imbalance in calling drm vma node allow() and drm vma node revoke() functions, which are related to memory management for mmap offset. This imbalance can lead to a memory leak because the per-file vm count may remain non-zero, causing the rbtree to be leaked. The issue occurs when the mmap offset is reused by the client.

Recommendations To resolve this issue, consider updating the Linux kernel to a version that includes the fix for the memory leak. Specifically, the drm vma node allow once() function should be called instead of drm vma node allow() to prevent the memory leak. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
