SubjectRe: [PATCH 1/2] aio: fix aio request leak when events are reaped by userspace
Date
Benjamin LaHaise <bcrl@kvack.org> writes:

> The aio cleanups and optimizations by kmo that were merged into the 3.10

> leading to the application being unable to submit further aio requests.
> This patch applies to 3.12+. A separate backport is required for 3.10/3.11.
> This issue was uncovered as part of CVE-2014-0206.
