Overview

CVE-2022-48754 is a high-severity vulnerability. It was published on June 20, 2024 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:

phylib: fix potential use-after-free

Commit bafbdd527d56 ("phylib: Add device reset GPIO support") added call

to phy_device_reset(phydev) after the put_device() call in phy_detach().

The comment before the put_device() call says that the phydev might go

away with put_device().

Fix potential use-after-free by calling phy_device_reset() before

put_device().

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.
