This leads to leaking the notify handler past driver removal, which may cause a kernel crash to occur if ACPI notify on the given device is triggered after removing the driver, and causes a subsequent probe of the given device with the same driver to fail. Address this by updating the acpi_remove_notify_handler() call in acpi_button_remove() as appropriate. The Linux kernel CVE team has assigned CVE-2026-64013 to this issue. Affected and fixed versions =========================== Issue introduced in 6.15 with commit a7e23ec17feecc7bac0d500cea900cace7b50129 and fixed in 7.0.12 with commit 614cb8c26c5aa53196ee9b211b76ee618b147d32 Issue introduced in 6.15 with commit a7e23ec17feecc7bac0d500cea900cace7b50129 and fixed in 7.1 with commit fe80251152fed5b185f795ef2cd9f7fe9c3162e0 Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. 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-2026-64013 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/acpi/button.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/614cb8c26c5aa53196ee9b211b76ee618b147d32 https://git.kernel.org/stable/c/fe80251152fed5b185f795ef2cd9f7fe9c3162e0
