https://notcve.org/view.php?id=CVE-2022-48696
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. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: regmap: spi: reserva de espacio para dirección/relleno de registro Actualmente, los límites max_raw_read y max_raw_write en la estructura regmap_spi no tienen en cuenta el tamaño adicional de la dirección de registro transmitida y el relleno. Esto puede dar como resultado que se exceda el tamaño de mensaje SPI máximo permitido, lo que podría causar un comportamiento indefinido, por ejemplo, corrupción de datos. Corrija regmap_get_spi_bus() para ajustar adecuadamente los límites mencionados anteriormente reservando espacio para la dirección/relleno del registro como se establece en la configuración de regmap. • https://git.kernel.org/stable/c/f231ff38b7b23197013b437128d196710fe282da https://git.kernel.org/stable/c/15ff1f17847c19174b260bd7dd0de33edcebd45e https://git.kernel.org/stable/c/f5723cfc01932c7a8d5c78dbf7e067e537c91439 •
