CVE-2023-52626

HIGH

Linux Kernel - Out-of-bounds Read in mlx5e Port Timestamping napi_poll Context

Title source: llm
STIX 2.1

Description

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.
