Описание
In the Android kernel in the video driver there is a use after free due to a race condition. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
A flaw was found in the Linux kernel's video driver. A race condition, leading to a use-after-free, could lead to a local privilege escalation. User interaction is not needed for exploitation.
Отчет
This issue is rated as having Moderate impact, because of the need of additional privileges (usually local console user) to access the video device driver.
Меры по смягчению последствий
To mitigate this issue, prevent modules v4l2-common, v4l2-dv-timings from being loaded if not being used for primary display. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically.
