Answer in brief
CVE-2026-93179 records a Unknown severity vulnerability in drm/amd/powerplay: fix VoltageObjectInfo zero-stride loop and OOB read. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic), Linux/Linux (generic), Linux/Linux (generic) and additional mapped packages. Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. 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/powerplay: fix VoltageObjectInfo zero-stride loop and OOB read Reject voltage objects whose usSize is smaller than the header or would advance the cursor past the table end, preventing an infinite loop or heap OOB read when the VBIOS supplies a malformed VoltageObjectInfo table.
