CVE-2019-19077

Una pérdida de memoria en la función bnxt_re_create_srq() en el archivo drivers/infiniband/hw/bnxt_re/ib_verbs.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 de la copia hacia udata, también se conoce como CID -4a9d46a9fe14.

A memory leak flaw was found in the Broadcom NetXtreme HCA driver in the Linux kernel, in the way it handled resource cleanup on the copy to userspace error. This flaw allows a local attacker to trigger this error and crash the system.

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.
