Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
usb: legacy: ncm: Fix NPE in gncm_bind<br />
<br />
Commit 56a512a9b410 ("usb: gadget: f_ncm: align net_device lifecycle<br />
with bind/unbind") deferred the allocation of the net_device. This<br />
change leads to a NULL pointer dereference in the legacy NCM driver as<br />
it attempts to access the net_device before it&#39;s fully instantiated.<br />
<br />
Store the provided qmult, host_addr, and dev_addr into the struct<br />
ncm_opts->net_opts during gncm_bind(). These values will be properly<br />
applied to the net_device when it is allocated and configured later in<br />
the binding process by the NCM function driver.
