Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A race condition exists in the NFC LLCP connection state machine. The issue occurs when a connection acceptance packet (CC) is processed concurrently with a socket release, potentially leading to a use-after-free of the socket object. Specifically, the function nfc llcp recv cc() moves a socket from the connecting sockets list to the sockets list without holding the socket lock. If llcp sock release() executes simultaneously, it may unlink the socket and drop its references, causing nfc llcp recv cc() to link a freed socket into the live list.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
