Answer in brief
CVE-2022-48979 records a High severity (CVSS 7.8) vulnerability in drm/amd/display: fix array index out of bound error in DCN32 DML. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.8. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
