So the best thing to do would be to assume\n  that if VMRUN fails, the actions requested in the control fields may not\n  have been performed.\n\n## Affected\n\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 8676b29d186fcb5c1251d8152fc91d19421e5600`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < e27fc915c8f575ab5630e27d97465c2077d4b9d1`\n- `Linux < 7.2.10`\n- `Linux (all versions)`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
