CVE-2019-15098

Published: 16 August 2019

drivers/net/wireless/ath/ath6kl/usb.c in the Linux kernel through 5.2.9 has a NULL pointer dereference via an incomplete address in an endpoint descriptor.

From the Ubuntu Security Team

Hui Peng discovered that the Atheros AR6004 USB Wi-Fi device driver for the Linux kernel did not properly validate endpoint descriptors returned by the device. A physically proximate attacker could use this to cause a denial of service (system crash).
