CVE-2023-52485
5.5 · MEDIUMOverview
CVE-2023-52485 is a medium-severity vulnerability affecting linux linux_kernel. It was published on February 29, 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/amd/display: Wake DMCUB before sending a command
[Why]
We can hang in place trying to send commands when the DMCUB isn't
powered on.
[How]
For functions that execute within a DC context or DC lock we can
wrap the direct calls to dm_execute_dmub_cmd/list with code that
exits idle power optimizations and reallows once we're done with
the command submission on success.
For DM direct submissions the DM will need to manage the enter/exit
sequencing manually.
We cannot invoke a DMCUB command directly within the DM execution
helper or we can deadlock.
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.
