CVE-2022-48696

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to the regmap component in the Linux kernel, specifically with the spi module. The max raw read and max raw write limits in the regmap spi struct do not account for the additional size of the transmitted register address and padding, potentially exceeding the maximum permitted SPI message size and causing undefined behavior, such as data corruption. The function regmap get spi bus() has been fixed to properly adjust these limits by reserving space for the register address and padding as set in the regmap configuration.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
