| Vector | AV:N/AC:L/Au:N/C:P/I:P/A:P |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a potential NULL pointer dereference in the
amdgpu dm fini() function. The adev->dm.dc variable might be NULL before the call to dc enable dmub notifications(), which could lead to a crash. The fix involves adding a NULL check before the call to ensure that adev->dm.dc is not NULL. Additionally, there were two separate checks for NULL in adev->dm.dc before dc deinit callbacks() and dc dmub srv destroy(), which have been combined into one check. The issue was found by the Linux Verification Center using a static analysis tool.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
