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

Description The issue is related to the misinterpretation of the get sg table return value in the Linux kernel's drivers/gpu/drm/arm/malidp planes.c file. This misinterpretation can lead to pointer dereference errors. The exploitation of this issue may allow an attacker to cause a denial of service.

Recommendations For Linux kernel versions prior to 5.19, update to version 5.19 or later to resolve the issue. As a temporary workaround, consider restricting access to the vulnerable malidp planes.c driver to minimize the risk of exploitation.
