    Summary:

    Details: 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.
