Descriptions

A memory leak in the sof_set_get_large_ctrl_data() function in sound/soc/sof/ipc.c in the Linux kernel through 5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering sof_get_ctrl_copy_params() failures, aka CID-45c1380358b1.

Una pérdida de memoria en la función sof_set_get_large_ctrl_data() en el archivo sound/soc/sof/ipc.c en el kernel de Linux versiones hasta 5.3.9, permite a atacantes causar una denegación de servicio (consumo de memoria) mediante la activación de fallos de la función sof_get_ctrl_copy_params(), también se conoce como CID-45c1380358b1.

A flaw was found in the Linux kernel’s
sof_set_get_large_ctrl_data function, in the way it handled memory cleanup in a specific error path. A local attacker could use this flaw to crash the system.
