CVE-2024-36960

drm/vmwgfx: Fix invalid reads in fence signaled events

State: Published
Severity: 7.1 High
Published: Jun 3, 2024
Updated: Aug 5, 2026
Reserved: May 30, 2024

Description

In the Linux kernel, the following vulnerability has been resolved:

drm/vmwgfx: Fix invalid reads in fence signaled events

Correctly set the length of the drm_event to the size of the structure that's actually used.

The length of the drm_event was set to the parent structure instead of to the drm_vmw_event_fence which is supposed to be read. drm_read uses the length parameter to copy the event to the user space thus resuling in oob reads.
