CVSS 3.1
5.5
MediumMetricsAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue arises when a PCI device with a non-VGA class is the boot display, and
sysfb disable() is not called for this device. However, when a non-primary GPU with a VGA class calls sysfb disable(), it results in a NULL pointer dereference because the resources have already been freed by aperture detach platform device(). This is fixed by passing a device pointer to sysfb disable() and checking the device to determine if the function should be executed.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
