CVE-2019-18811

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.

It was discovered that the Linux kernel did not properly clear data structures on context switches for certain Intel graphics processors. A local attacker could use this to expose sensitive information. It was discovered that the Atheros 802.11ac wireless USB device driver in the Linux kernel did not properly validate device metadata. A physically proximate attacker could use this to cause a denial of service. Various other issues were also addressed.
