5.5 · MEDIUM

In the Linux kernel, the following vulnerability has been resolved: i3c: master: mipi-i3c-hci: Fix a kernel panic for accessing DAT_data.

Published May 21, 2024EPSS 0.24%

Overview

CVE-2023-52763 is a medium-severity vulnerability. It was published on May 21, 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:

i3c: master: mipi-i3c-hci: Fix a kernel panic for accessing DAT_data.

The `i3c_master_bus_init` function may attach the I2C devices before the

I3C bus initialization. In this flow, the DAT `alloc_entry`` will be used

before the DAT `init`. Additionally, if the `i3c_master_bus_init` fails,

the DAT `cleanup` will execute before the device is detached, which will

execue DAT `free_entry` function. The above scenario can cause the driver

to use DAT_data when it is NULL.

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.
