If either fails, the error path jumps to err_close which calls hid_hw_close()/hid_hw_stop() without first calling hid_device_io_stop(). hid_hw_stop() does not stop device IO, so hid_input_report() may still run and access driver data that is being torn down, resulting in a use-after-free. Add an err_io_stop label that calls hid_device_io_stop() before hid_hw_close(), and point the two post-io_start error paths at it. The Linux kernel CVE team has assigned CVE-2026-80770 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/hid/hid-nintendo.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/c2f3d51c7f5222f5b51e0c90f02258d82e1b44dd https://git.kernel.org/stable/c/c023443f0e6cfd257846b6515c93c1ea08026593 https://git.kernel.org/stable/c/03a84f9f88b42cd49752ec0259922b67e4b88598 https://git.kernel.org/stable/c/5efcd7bbfaaec67d137c99aa0940fa34375db27f https://git.kernel.org/stable/c/13a3edf96568a0b7aacadea07c2adec53ac8f630 https://git.kernel.org/stable/c/2e0d98dc8a6dea5fc2b72bf66e0dcbd5488644b4 https://git.kernel.org/stable/c/1f74d3bff6fe04a64e02ab3661d2e0d554565aa6
