FKIE_CVE-2022-48979

Vulnerability from fkie_nvd - Published: 2024-10-21 20:15 - Updated: 2024-10-25 18:40
Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: fix array index out of bound error in DCN32 DML [Why&How] LinkCapacitySupport array is indexed with the number of voltage states and not the number of max DPPs. Fix the error by changing the array declaration to use the correct (larger) array size of total number of voltage states.
