In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: MGMT: validate LTK enc_size on load
Load Long Term Keys stores the user-provided enc_size and later uses it to size fixed-size stack operations when replying to LE LTK requests. An enc_size larger than the 16-byte key buffer can therefore overflow the reply stack buffer.
Reject oversized enc_size values while validating the management LTK record so invalid keys never reach the stored key state.
