5.5 · MEDIUMOverview
CVE-2024-43867 is a medium-severity vulnerability affecting linux linux_kernel. It was published on August 21, 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/nouveau: prime: fix refcount underflow
Calling nouveau_bo_ref() on a nouveau_bo without initializing it (and
hence the backing ttm_bo) leads to a refcount underflow.
Instead of calling nouveau_bo_ref() in the unwind path of
drm_gem_object_init(), clean things up manually.
(cherry picked from commit 1b93f3e89d03cfc576636e195466a0d728ad8de5)
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
