Description

In the Linux kernel, the following vulnerability has been resolved:
media: uvcvideo: Remove dangling pointers
When an async control is written, we copy a pointer to the file handle
that started the operation. That pointer will be used when the device is
done. Which could be anytime in the future.
If the user closes that file descriptor, its structure will be freed,
and there will be one dangling pointer per pending async control, that
the driver will try to use.
Clean all the dangling pointers during release().
To avoid adding a performance penalty in the most common case (no async
operation), a counter has been introduced with some logic to make sure
that it is properly handled.
A dangling pointer vulnerability was found in the Linux kernel. When an async control is written, a copy of a pointer is made in the file handle that started the operation. If the user closes that file descriptor, its structure will be freed and there will be one dangling pointer per pending async control that the driver will try to use, leading to denial of service of the system.
