Out-of-bounds read via unchecked HID event lengths
Published Sep 11, 2026 · Updated Sep 11, 2026
Out-of-bounds reads in Linux 6.13 allow physically proximate attackers to trigger kernel memory reads via malformed Corsair HID events. The corsair_void_raw_event function indexed bytes 1 through 4 of short status or firmware reports without first requiring the documented five-byte length. Reachability requires a connected Corsair Void HID device capable of supplying a malformed report; published evidence establishes the invalid read but not disclosure or a crash.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
