CVE-2026-80573

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.
