Summary
wifi: avoid kernel-infoleak from struct iw_point
Details

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

wifi: avoid kernel-infoleak from struct iw_point

struct iw_point has a 32bit hole on 64bit arches.

struct iw_point { void __user pointer; / Pointer to the data (in user space) / __u16 length; / number of fields or size in bytes / __u16 flags; / Optional params */ };

Make sure to zero the structure to avoid disclosing 32bits of kernel data to user space.
