The interface need to be released before unregistering hci device when usb disconnect. Removing BT usb dongle without properly releasing the interface may cause Kernel panic while unregister hci device. The Linux kernel CVE team has assigned CVE-2024-56757 to this issue. Affected and fixed versions =========================== Fixed in 6.12.8 with commit cc569d791ab2a0de74f76e470515d25d24c9b84b Fixed in 6.13-rc1 with commit 489304e67087abddc2666c5af0159cb95afdcf59 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-2024-56757 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/bluetooth/btusb.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/cc569d791ab2a0de74f76e470515d25d24c9b84b https://git.kernel.org/stable/c/489304e67087abddc2666c5af0159cb95afdcf59
