CWE ID 401
Summary
CVE-2023-53001 is a vulnerability affecting the Linux kernel that allows drm drivers to safely check and grant drm_vma_node access for a drm file only once, without the need to keep track of each granted permission and revoke it subsequently to prevent memory leaks. Prior to this resolution, there was no easy way for drm drivers to ensure they didn't exceed the number of allowed nodes, potentially leading to memory leaks. The new function, drm_vma_node_allow_once(), has been introduced to address this issue.
