How to fix?

Upgrade RHEL:9 kernel-core to version 0:5.14.0-284.77.1.el9_2 or higher.
This issue was patched in RHSA-2024:5066.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-core package and not the kernel-core package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

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.
