Summary
Bluetooth: L2CAP: do not leave dangling sk pointer on error in l2cap_sock_create()
Details

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

Bluetooth: L2CAP: do not leave dangling sk pointer on error in l2capsockcreate()

btsockalloc() allocates the sk object and attaches it to the provided sock object. On error l2capsockalloc() frees the sk object, but the dangling pointer is still attached to the sock object, which may create use-after-free in other code.
