CVE-2019-19078

Una pérdida de memoria en la función ath10k_usb_hif_tx_sg() en el archivo drivers/net/wireless/ath/ath10k/usb.c en el kernel de Linux versiones hasta la versión 5.3.11, permite a atacantes causar una denegación de servicio (consumo de memoria) al desencadenar fallos de la función usb_submit_urb(), también se conoce como CID-b8d17e7d93d2.

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. It was discovered that a race condition existed in the Virtual Video Test Driver in the Linux kernel. An attacker with write access to /dev/video0 on a system with the vivid module loaded could possibly use this to gain administrative privileges. Various other issues were also addressed.
