UBUNTU-CVE-2026-80573: Medium severity ubuntu/linux vulnerability

Published Aug 26, 2026
·
Updated

In the Linux kernel, the following vulnerability has been resolved: Input: iforce - validate input packet lengths iforceprocesspacket() 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.
