This eliminates the\npossibility of getting an out-of-bounds fault.\n\nAdd a warning message if the HID descriptor contains any unsupported\noptional HID class descriptors.\n\n## Affected\n\n- `Linux >= f043bfc98c193c284e2cd768fefabe18ac2fed9b < 7a6d6b68db128da2078ccd9a751dfa3f75c9cf5b`\n- `Linux >= f043bfc98c193c284e2cd768fefabe18ac2fed9b < 41827a2dbdd7880df9881506dee13bc88d4230bb`\n- `Linux >= f043bfc98c193c284e2cd768fefabe18ac2fed9b < 1df80d748f984290c895e843401824215dcfbfb0`\n- `Linux >= f043bfc98c193c284e2cd768fefabe18ac2fed9b < a8f842534807985d3a676006d140541b87044345`\n- `Linux >= f043bfc98c193c284e2cd768fefabe18ac2fed9b < 4fa7831cf0ac71a0a345369d1a6084f2b096e55e`\n- `Linux >= f043bfc98c193c284e2cd768fefabe18ac2fed9b < 74388368927e9c52a69524af5bbd6c55eb4690de`\n- `Linux >= f043bfc98c193c284e2cd768fefabe18ac2fed9b < 485e1b741eb838cbe1d6b0e81e5ab62ae6c095cf`\n- `Linux >= f043bfc98c193c284e2cd768fefabe18ac2fed9b < fe7f7ac8e0c708446ff017453add769ffc15deed`\n- `Linux 99de0781e0de7c866f762b931351c2a501c3074f`\n- `Linux 8d675aa967d3927ac100f7af48f2a2af8a041d2d`\n- `Linux f4cf5d75416ae3d79e03179fe6f4b9f1231ae42c`\n- `Linux 439f76690d7d5dd212ea7bebc1f2fa077e3d645d`\n- `Linux 2929cb995378205bceda86d6fd3cbc22e522f97f`\n- `Linux 57265cddde308292af881ce634a5378dd4e25900`\n- `Linux 984154e7eef1f9e543dabd7422cfc99015778732`\n- `Linux >= 3.2.95 < 3.3`\n- `Linux >= 3.16.50 < 3.17`\n- `Linux >= 3.18.76 < 3.19`\n- `Linux >= 4.1.46 < 4.2`\n- `Linux >= 4.4.93 < 4.5`\n- `Linux >= 4.9.57 < 4.10`\n- `Linux >= 4.13.8 < 4.14`\n- `Linux 4.14`\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":[]}
