High
| 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 nullptr dereference in the Linux kernel's drm/msm/a6xx component when the speedbin setting fails. This occurs when
a6xx destroy() is called before adreno gpu init(), leading to a null pointer dereference in msm gpu cleanup() due to gpu->pdev being assigned only in a6xx gpu init(). The problem is resolved by explicitly de-allocating the LLC data and freeing a6xx gpu instead of relying on null checks. There is no information provided about the estimated number of potentially affected devices or real-world incidents where this issue was exploited.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
