Overview

CVE-2023-52510 is a high-severity vulnerability. It was published on March 2, 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:

ieee802154: ca8210: Fix a potential UAF in ca8210_probe

If of_clk_add_provider() fails in ca8210_register_ext_clock(),

it calls clk_unregister() to release priv->clk and returns an

error. However, the caller ca8210_probe() then calls ca8210_remove(),

where priv->clk is freed again in ca8210_unregister_ext_clock(). In

this case, a use-after-free may happen in the second time we call

clk_unregister().

Fix this by removing the first clk_unregister(). Also, priv->clk could

be an error code on failure of clk_register_fixed_rate(). Use

IS_ERR_OR_NULL to catch this case in ca8210_unregister_ext_clock().

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.
