CVE-2026-64178

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: bnep: Fix UAF read of dev->name

bnep_add_connection() needs to keep holding the bnep_session_sem while

reading dev->name (just like bnep_get_connlist() does); otherwise the

bnep_session() thread can concurrently free the net_device, which can for

example be triggered by a concurrent bnep_del_connection().

(This UAF is fairly uninteresting from a security perspective;

calling bnep_add_connection() requires passing a capable(CAP_NET_ADMIN)

check. It also requires completely tearing down a netdev during a fairly

tight race window.)
