Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description An issue exists in the Bluetooth component where HCI UART PROTO INIT is not cleared when hci register dev() fails within the hci uart register dev() function. This failure allows incoming UART data to reach the protocol-specific receive handler in hci uart tty receive() after resources have been freed, potentially leading to a null pointer dereference.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
