| 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 5.19.0-stb-cbq #19
Description
A flaw exists in the DRM framework where a double disable condition can occur if user space issues an extra screen update immediately after closing the DRM device while the downstream display interface is disabled. This can lead to a crash within the
dp bridge disable() function when attempting to access the main link register while the main link clocks are disabled. The issue arises from a lack of protection in the DRM framework to prevent re-disabling a display pipeline that is already disabled, relying on user-mode control of the crtc->active state.Recommendations
Update to Linux kernel version 5.19.0-stb-cbq #19 or later.
