| Vector | AV: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 versions prior to 6.6.50
Description
The issue is related to a null pointer dereference in the
psb intel lvds get modes() function. Specifically, the return value of drm mode duplicate() is assigned to mode, which can lead to a null pointer dereference if drm mode duplicate() fails. To avoid this, a check has been added.Recommendations
Update to Linux kernel version 6.6.50 or later to resolve the issue.
As a temporary workaround, consider disabling the
psb intel lvds get modes() function until a patch is available.
Restrict access to the drm/gma500 component to minimize the risk of exploitation.Exploit
