Overview

CVE-2022-48703 is a medium-severity vulnerability. It was published on May 3, 2024 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:

thermal/int340x_thermal: handle data_vault when the value is ZERO_SIZE_PTR

In some case, the GDDV returns a package with a buffer which has

zero length. It causes that kmemdup() returns ZERO_SIZE_PTR (0x10).

Then the data_vault_read() got NULL point dereference problem when

accessing the 0x10 value in data_vault.

[ 71.024560] BUG: kernel NULL pointer dereference, address:

0000000000000010

This patch uses ZERO_OR_NULL_PTR() for checking ZERO_SIZE_PTR or

NULL value in data_vault.

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.
