In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: clear iso_data always when detaching conn from hcon When setting conn->hcon = NULL, also conn->hcon->iso_data = NULL is necessary, otherwise later iso_conn_free() w...

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: fix UAF in l2cap_le_connect_rsp l2cap_le_connect_rsp() obtains a channel via __l2cap_get_chan_by_ident() but neither holds a reference nor uses l2cap_chan_hold_un...

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: lock sk in iso_sock_getname Accessing iso_pi(sk)->conn requires lock_sock, which is not held here. Fix by adding the lock/release.

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: lock sk in iso_connect_ind Accessing iso_pi(sk)->conn requires lock_sock, which is not taken in the "ev3" part of iso_connect_ind. It may also be NULL if socket ha...

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: hold sk properly in iso_conn_ready sk deref in iso_conn_ready must be done either under conn->lock, or holding a refcount, to avoid concurrent close. conn->sk is cu...
