      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: l2cap: Add missing chan lock in l2cap_ecred_reconf_rsp\n\nl2cap_ecred_reconf_rsp() calls l2cap_chan_del() without holding\nl2cap_chan_lock(). Every other l2cap_chan_del() caller in the file\nacquires the lock first. A remote BLE device can send a crafted\nL2CAP ECRED reconfiguration response to corrupt the channel list\nwhile another thread is iterating it.\n\nAdd l2cap_chan_hold() and l2cap_chan_lock() before l2cap_chan_del(),\nand l2cap_chan_unlock() and l2cap_chan_put() after, matching the\npattern used in l2cap_ecred_conn_rsp() and l2cap_conn_del().",
