CVE-2026-80573
Description
AI Translation Available
In 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.
