Overview

CVE-2025-37910 is a medium-severity vulnerability. It was published on May 20, 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:

ptp: ocp: Fix NULL dereference in Adva board SMA sysfs operations

On Adva boards, SMA sysfs store/get operations can call

__handle_signal_outputs() or __handle_signal_inputs() while the `irig`

and `dcf` pointers are uninitialized, leading to a NULL pointer

dereference in __handle_signal() and causing a kernel crash. Adva boards

don't use `irig` or `dcf` functionality, so add Adva-specific callbacks

`ptp_ocp_sma_adva_set_outputs()` and `ptp_ocp_sma_adva_set_inputs()` that

avoid invoking `irig` or `dcf` input/output routines.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
