Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a NULL pointer dereference in the Linux kernel's drm/bridge/ite-it66121.c component. This occurs when no monitor is connected and the sound card is opened from userspace. The vulnerability allows an attacker to cause a denial of service. To mitigate this, the kernel now returns an empty buffer of zeroes as the EDID information to the sound framework when there is no connector attached.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
