This vulnerability has been fixed in the Linux kernel. Users and administrators should apply the official Linux kernel updates containing the fixes identified by the listed commit hashes. No additional mitigation is required once the kernel is updated.
Description
A vulnerability in the Linux kernel Bluetooth subsystem's raw HCI socket security filter allowed unprivileged sockets to submit out-of-range OCF values that alias allowlisted commands, potentially bypassing security checks. This flaw was due to masking the 10-bit OCF with 127, causing reserved OCFs to be treated as valid commands. The issue has been fixed by rejecting OCF values that cannot be represented by the security filter instead of aliasing them.
