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. The Linux kernel CVE team has assigned CVE-2026-80573 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/input/joystick/iforce/iforce-packets.c drivers/input/joystick/iforce/iforce-usb.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/0ec411167655ef3ff3e84f6af685e962aff9a75b https://git.kernel.org/stable/c/609be40988898a4d75225ade0ea5c1734757dd33 https://git.kernel.org/stable/c/e73d7a7d913d89141321f5f3f16343ecc200d152 https://git.kernel.org/stable/c/5232529eaf57f08fe37484e301579a1915b93d14 https://git.kernel.org/stable/c/2c083ab16e33fbff3ab8c752fbf8118ed3dd31ce https://git.kernel.org/stable/c/a64a8b6b31cd669f0449138e53cc2592d454ccf1 https://git.kernel.org/stable/c/84e5cb517f445dadbd5f8bf4ec513540e51f9c36 https://git.kernel.org/stable/c/5751c781d3c97ab6ce0e2a966156ed882152c415
