GHSA-2CC7-72RV-6M2M
Vulnerability from github – Published: 2026-08-27 06:31 – Updated: 2026-08-27 06:31In the Linux kernel, the following vulnerability has been resolved:
Input: iforce - validate input packet lengths
iforce_process_packet() reads fixed fields from joystick, wheel and status packets without first checking their lengths. In particular, the shared hats-and-buttons helper unconditionally reads data[6]. The status tail is a sequence of 16-bit effect addresses, but an incomplete final address is also consumed. A successful zero-length USB URB additionally reads the packet ID before the common parser is called.
Reject the zero-length USB transfer, require the seven-byte joystick and wheel prefixes and the two-byte status prefix, and consume only complete status-tail addresses.
