GHSA-F6PW-2J25-JJ48

Vulnerability from github – Published: 2025-07-04 15:31 – Updated: 2025-11-18 18:32

Details

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

drm/amd/display: Avoid divide by zero by initializing dummy pitch to 1

[Why] If the dummy values in populate_dummy_dml_surface_cfg() aren't updated then they can lead to a divide by zero in downstream callers like CalculateVMAndRowBytes()

[How] Initialize dummy value to a value to avoid divide by zero.

Severity ?

5.5 (Medium)
