Pending analysis
Type:
CWE-125 Out-of-bounds Read
Publication date:

Description

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