Return -EFAULT without\nunwinding that state, leaving inconsistent trap state and a refcount\nimbalance that could break later DISABLE/ENABLE.\n\nOn copy_to_user failure, deactivate the trap and undo the rest of the\nenable setup before returning.\n\n## Affected\n\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 641be20110cdfb6d921605adb42a764a0fccac54`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 656a40bdc20def58790b8512e6000195436d8855`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 1b39f46eec2f907417d4955bb88434170f94a8d8`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 01112e241e37f9ac98b6f418d93ce2e0b87b7ee0`\n- `Linux < 6.6.158`\n- `Linux < 6.12.111`\n- `Linux < 6.18.53`\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":[]}
