CVE-2023-52825

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

Description The issue is related to a race condition in the drm/amdkfd component of the Linux kernel, specifically in the svm code. This condition can lead to a "use-after-free" error, potentially allowing an attacker to elevate their privileges. The vulnerability is caused by the unref operation of svm bo happening in both mmu callback and a callback after migrating to system RAM, which are asynchronous calls in different tasks. To avoid this issue, the svm bo unref operation needs to be synchronized.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
