This can cause confusion in the HID core resulting in nasty\nside-effects such as OOB writes.\n\nAdd a check to ensure that the report ID in the response, matches the\none that was requested.  If it doesn't, omit reporting the raw event and\nreturn early.\n\n## Affected\n\n- `Linux >= 6d4f5440a3a2bb2e9d0d582bbf98234e9e9bb095 < 516da3f25cfe18643835af1cf09b0e9ffc36c383`\n- `Linux >= 6d4f5440a3a2bb2e9d0d582bbf98234e9e9bb095 < a61163daf8a90b4a7ef154d5fc9c525f665734e3`\n- `Linux >= 6d4f5440a3a2bb2e9d0d582bbf98234e9e9bb095 < 74c6015375d8b9bc1b1eb79f20636c8e894bcad7`\n- `Linux >= 6d4f5440a3a2bb2e9d0d582bbf98234e9e9bb095 < c7a27bb4d0f6573ca0f9c7ef0b63291486239190`\n- `Linux >= 6d4f5440a3a2bb2e9d0d582bbf98234e9e9bb095 < 6a4acd3e86fe5584050c213d95147eba33856033`\n- `Linux >= 6d4f5440a3a2bb2e9d0d582bbf98234e9e9bb095 < 7f66fdbc077faed3b52519228d21d81979e92249`\n- `Linux >= 6d4f5440a3a2bb2e9d0d582bbf98234e9e9bb095 < 2edc92f89eee328b5be5706b5d431bf90669e9c0`\n- `Linux >= 6d4f5440a3a2bb2e9d0d582bbf98234e9e9bb095 < e716edafedad4952fe3a4a273d2e039a84e8681a`\n- `Linux fee906f035f0bd18ff12d84d58766c44a2ab0918`\n- `Linux >= 4.3.6 < 4.4`\n- `Linux 4.4`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":43,"depthScoreParts":{"impact":42.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
