Description
In the Linux kernel, the following vulnerability has been resolved:
media: iris: Fix memory leak by freeing untracked persist buffer
One internal buffer which is allocated only once per session was not
being freed during session close because it was not being tracked as
part of internal buffer list which resulted in a memory leak.
Add the necessary logic to explicitly free the untracked internal buffer
during session close to ensure all allocated memory is released
properly.
