| Vector | AV:L/AC:L/Au:S/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw in the drm/amd/display subsystem related to cursor attribute functions. Specifically, the
dc stream set cursor attributes() function dereferences the stream pointer and nested members without proper NULL pointer checks. While callers of these functions generally perform NULL checks, the refactored code introduced an unchecked dereference. The dc stream check cursor attributes() function previously checked for NULL streams but this check was removed. The vulnerable function is dc stream set cursor attributes(). The vulnerable parameter is stream.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
