Fix by skipping the increment when there\nare more power domains than regulators.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · updated 2026-09-29 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-93272.json)","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":30.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":212331,"id":"CVE-2026-93272","ts":1790668150413,"field":"cvss","old":null,"new":"5.5"},{"seq":212330,"id":"CVE-2026-93272","ts":1790668150413,"field":"severity","old":"none","new":"medium"}]}
