Published Mar 27, 2025CWE-459EPSS 0.25%

Overview

CVE-2023-52929 is a medium-severity vulnerability. It was published on March 27, 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:

nvmem: core: fix cleanup after dev_set_name()

If dev_set_name() fails, we leak nvmem->wp_gpio as the cleanup does not

put this. While a minimal fix for this would be to add the gpiod_put()

call, we can do better if we split device_register(), and use the

tested nvmem_release() cleanup code by initialising the device early,

and putting the device.

This results in a slightly larger fix, but results in clear code.

Note: this patch depends on "nvmem: core: initialise nvmem->id early"

and "nvmem: core: remove nvmem_config wp_gpio".

[Srini: Fixed subject line and error code handing with wp_gpio while applying.]

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.
