Overview

CVE-2023-53242 is a high-severity vulnerability. It was published on September 15, 2025 and has a CVSS 3.1 base score of 7.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.1, 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:

thermal/drivers/hisi: Drop second sensor hi3660

The commit 74c8e6bffbe1 ("driver core: Add __alloc_size hint to devm

allocators") exposes a panic "BRK handler: Fatal exception" on the

hi3660_thermal_probe funciton.

This is because the function allocates memory for only one

sensors array entry, but tries to fill up a second one.

Fix this by removing the unneeded second access.

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.
