Overview

CVE-2023-53308 is a high-severity vulnerability. It was published on September 16, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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:

net: fec: Better handle pm_runtime_get() failing in .remove()

In the (unlikely) event that pm_runtime_get() (disguised as

pm_runtime_resume_and_get()) fails, the remove callback returned an

error early. The problem with this is that the driver core ignores the

error value and continues removing the device. This results in a

resource leak. Worse the devm allocated resources are freed and so if a

callback of the driver is called later the register mapping is already

gone which probably results in a crash.

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.
