Description
Description
In the Linux kernel, the following vulnerability has been resolved:
HID: prodikeys: Check presence of pm->input_ep82
Fake USB devices can send their own report descriptors for which the
input_mapping() hook does not get called. In this case, pm->input_ep82 stays
NULL, which leads to a crash later.
This does not happen with the real device, but can be provoked by imposing as
one.
