CVE-2024-36960 Open this link in a new tabHow to fix?
Upgrade RHEL:8 perf to version 0:4.18.0-553.16.1.el8_10 or higher.
This issue was patched in RHSA-2024:5101.
NVD Description
Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by RHEL.
See How to fix? for RHEL:8 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.
