In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: Fix operation precedence bug in port timestamping napi_poll
context Indirection (*) is of lower precedence than postfix increment (++).
Logic in napi_poll context would cause an out-of-bound read by first
increment the pointer address by byte address space and then dereference
the value. Rather, the intended logic was to dereference first and then
increment the underlying value.
