A sparse class value is absorbed by\npolicydb_class_isvalid() and its siblings; booleans have no such\npredicate, and no consumer that could use one.\n\nReject a boolean value that no boolean defines, once, where the array is\nbuilt. Conforming policies define every boolean they declare and are\nunaffected.\n\n## Affected\n\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 4d0ece18e648bd4362704fd087249ac697f2b7fb`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 3938c8494d3c5d84a53fd7d1966ae9dde46cb5f8`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 4dfb997c60f7951011d3dcbee926e3a7f80d8a76`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 3161daa3f1e3ca68f8b2b8fa01720b5a8dcc6b40`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 740012aebdb8311332bf66e2aabf453ba73c2c45`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 42a7107f99d86a7524c37f108047dfa3db096ab5`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < ed901e88aa3fb3d5d7b0b52c2ee3073209df9bec`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < a93d37a09b863810653f93d371fb197457d59deb`\n- `Linux 2.6.12`\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":[]}
