Описание
An issue was discovered in the stv06xx subsystem in the Linux kernel before 5.6.1. drivers/media/usb/gspca/stv06xx/stv06xx.c and drivers/media/usb/gspca/stv06xx/stv06xx_pb0100.c mishandle invalid descriptors, as demonstrated by a NULL pointer dereference, aka CID-485b06aadb93.
A flaw was found in the way the stv06xx driver in the Linux kernel handled certain types of USB descriptors. This flaw allows an attacker with the ability to induce the error conditions to crash the system.
Отчет
This issue is rated as having Low impact because of the preconditions needed to trigger the issue (physical access).
Меры по смягчению последствий
In order to mitigate this issue it is possible to prevent the affected code from being loaded by blacklisting the kernel module gspca_stv06xx. For instructions relating to how to blacklist a kernel module refer to: https://access.redhat.com/solutions/41278 .
