A response larger than that overflows buf with device-controlled content. The intel-quicki2c sibling already passes the caller length down to quicki2c_get_report() and validates the response against it before the copy. Do the same here. The Linux kernel CVE team has assigned CVE-2026-89619 to this issue.

Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2026-89619 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/hid/intel-thc-hid/intel-quickspi/quickspi-hid.c drivers/hid/intel-thc-hid/intel-quickspi/quickspi-protocol.c drivers/hid/intel-thc-hid/intel-quickspi/quickspi-protocol.h 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/72706b44b665679d7d60a488d8776a911f1a93f3 https://git.kernel.org/stable/c/54e0bafc0653bdf2a6c5f5f8ad8787a820d98663 https://git.kernel.org/stable/c/035ec4a71cb8020a927c123bbe75c2f88d614986
