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.

A flaw was found in the Linux kernel's iforce driver, which handles input devices such as joysticks and wheels. This vulnerability occurs because the iforce_process_packet() function processes incoming data packets without adequately validating their lengths. A local attacker could exploit this by sending specially crafted input packets or a zero-length USB Request Block (URB). This could lead to an out-of-bounds read, potentially causing a denial of service or system instability.
