Overview

CVE-2023-53654 is a medium-severity vulnerability. It was published on October 7, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

octeontx2-af: Add validation before accessing cgx and lmac

with the addition of new MAC blocks like CN10K RPM and CN10KB

RPM_USX, LMACs are noncontiguous and CGX blocks are also

noncontiguous. But during RVU driver initialization, the driver

is assuming they are contiguous and trying to access

cgx or lmac with their id which is resulting in kernel panic.

This patch fixes the issue by adding proper checks.
