Summary
xsk: fix an integer overflow in xp_create_and_assign_umem()
Details

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

xsk: fix an integer overflow in xpcreateandassignumem()

Since the i and pool->chunk_size variables are of type 'u32', their product can wrap around and then be cast to 'u64'. This can lead to two different XDP buffers pointing to the same memory area.

Found by InfoTeCS on behalf of Linux Verification Center (linuxtesting.org) with SVACE.
