- Summary
- regmap: spi: Reserve space for register address/padding
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
regmap: spi: Reserve space for register address/padding
Currently the maxrawread and maxrawwrite 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 regmapgetspi_bus() to properly adjust the above mentioned limits by reserving space for the register address/padding as set in the regmap configuration.
