The channel would be removed from the list in short period of time but be a bit more straight-forward here and just check for NULL instead of changing the order of function calls.</p> <p>Found by Linux Verification Center (linuxtesting.org) with SVACE static analysis tool.</p> <p><strong>Affected:</strong> Linux, Siemens SIMATIC S7-1500 TM MFP - GNU/Linux subsystem</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>Bluetooth: L2CAP: handle NULL sock pointer in l2cap_sock_alloc</p> <p>A NULL sock pointer is passed into l2cap_sock_alloc() when it is called from l2cap_sock_new_connection_cb() and the error handling paths should also be aware of it.</p> <p>Seemingly a more elegant solution would be to swap bt_sock_alloc() and l2cap_chan_create() calls since they are not interdependent to that moment but then l2cap_chan_create() adds the soon to be deallocated and still dummy-initialized channel to the global list accessible by many L2CAP paths.
