5.5 · MEDIUM

In the Linux kernel, the following vulnerability has been resolved: i2c: smbus: fix NULL function pointer dereference Baruch reported an OOPS when using the designware controller as target only.

Published May 20, 2024CWE-476EPSS 0.26%

Overview

CVE-2024-35984 is a medium-severity vulnerability. It was published on May 20, 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:

i2c: smbus: fix NULL function pointer dereference

Baruch reported an OOPS when using the designware controller as target

only. Target-only modes break the assumption of one transfer function

always being available. Fix this by always checking the pointer in

__i2c_transfer.

[wsa: dropped the simplification in core-smbus to avoid theoretical regressions]

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.
