Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description An issue exists in the Bluetooth ISO implementation where ISO sockets may dereference the hcon reference after the iso conn del() function has been called. This occurs because the clearing of iso conn::hcon previously depended on iso conn del() releasing the final reference to the iso conn, potentially leading to race conditions regarding reference ownership.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
