The cleanup path passes that error pointer to\npage_pool_destroy() instead of destroying the header page pool. This\ncan dereference the error pointer and leave the header page pool\nallocated.\n\nDestroy the header page pool instead.\n\n## Affected\n\n- `Linux >= 8a11010fdd9615e8dbb2f5d562ab88caa8a9516a < f4277b19edbc6abc9e1db7d6f6148608e8cb3c34`\n- `Linux >= 8a11010fdd9615e8dbb2f5d562ab88caa8a9516a < 4bab07f7b74e59bb26032fa5ff6969d63e1c52ef`\n- `Linux >= 8a11010fdd9615e8dbb2f5d562ab88caa8a9516a < 8e0b235bd918d06f54ba8fddd2c3ddc36ca59c15`\n- `Linux 6.18`\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":[]}
