n the Linux kernel, the following vulnerability has been resolved: crypto: qat - validate slices count returned by FW The function adf_send_admin_tl_start() enables the telemetry (TL) feature on a QAT device by sending the ICP_QAT_FW_TL_START message to the firmware. This triggers the FW to start writing TL data to a DMA buffer in memory and returns an array containing the number of accelerators of each type (slices) supported by this HW. The pointer to this array is stored in the adf_tl_hw_data data structure called slice_cnt. The array slice_cnt is then used in the function tl_print_dev_data() to report in debugfs only statistics about the supported accelerators. An incorrect value of the elements in slice_cnt might lead to an out of bounds memory read. At the moment, there isn't an implementation of FW that returns a wrong value, but for robustness validate the slice count array returned by FW.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: crypto: qat: valida el recuento de segmentos devueltos por el FW. La función adf_send_admin_tl_start() habilita la función de telemetría (TL) en un dispositivo QAT enviando el mensaje ICP_QAT_FW_TL_START al firmware. Esto hace que el FW comience a escribir datos TL en un búfer DMA en la memoria y devuelve una matriz que contiene la cantidad de aceleradores de cada tipo (porciones) admitidos por este HW. El puntero a esta matriz se almacena en la estructura de datos adf_tl_hw_data llamada slice_cnt. La matriz slice_cnt luego se usa en la función tl_print_dev_data() para informar en debugfs solo estadísticas sobre los aceleradores admitidos. Un valor incorrecto de los elementos en slice_cnt podría provocar una lectura de memoria fuera de los límites. Por el momento, no existe una implementación de FW que devuelva un valor incorrecto, pero para mayor solidez, valide la matriz de recuento de sectores devuelta por FW.
