Описание
In the Android kernel in the video driver there is a kernel pointer leak due to a WARN_ON statement. This could lead to local information disclosure with System execution privileges needed. User interaction is not needed for exploitation.
A flaw was found in the Linux kernel's video driver. A kernel pointer lead, due to a WARN_ON statement could lead to a local information disclosure with system execution privileges. User interaction is not needed for exploitation. The highest threat from this vulnerability is to data confidentiality.
Отчет
This issue is marked as having Low impact because the information leak is very subtle and can be only used to break KASLR and not provide access to kernel memory content.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
