Описание
An issue was discovered in the Linux kernel before 5.1.17. There is a NULL pointer dereference caused by a malicious USB device in the sound/usb/line6/pcm.c driver.
A NULL pointer dereference flaw was found in the way the LINE6 drivers in the Linux kernel allocated buffers for USB packets. This flaw allows an attacker with physical access to the system to crash the system.
Отчет
This issue is rated as having Low impact because of the physical access needed to trigger this issue.
Меры по смягчению последствий
To mitigate this issue, prevent module snd-usb-line6 from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically.
