Overview

CVE-2022-48696 is a high-severity vulnerability. It was published on May 3, 2024 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:

regmap: spi: Reserve space for register address/padding

Currently the max_raw_read and max_raw_write limits in regmap_spi struct

do not take into account the additional size of the transmitted register

address and padding. This may result in exceeding the maximum permitted

SPI message size, which could cause undefined behaviour, e.g. data

corruption.

Fix regmap_get_spi_bus() to properly adjust the above mentioned limits

by reserving space for the register address/padding as set in the regmap

configuration.

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.
