net/mlx5e: Fix operation precedence bug in port timestamping napi_poll context
概要
net/mlx5e: Fix operation precedence bug in port timestamping napi_poll context
原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
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.
