In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
isdn: mISDN: hfcsusb: fix memory leak in hfcsusb_probe()<br />
<br />
In hfcsusb_probe(), the memory allocated for ctrl_urb gets leaked when<br />
setup_instance() fails with an error code. Fix that by freeing the urb<br />
before freeing the hw structure. Also change the error paths to use the<br />
goto ladder style.<br />
<br />
Compile tested only. Issue found using a prototype static analysis tool.
