Subject: [PATCH 01/10] io_uring/rsrc: use nospec'ed indexes
Date: Thu, 13 Apr 2023 15:28:05 +0100 [thread overview]
Message-ID: <f02fafc5a9c0dd69be2b0618c38831c078232ff0.1681395792.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>
We use array_index_nospec() for registered buffer indexes, but don't use
it while poking into rsrc tags, fix that.
Fixes: 634d00df5e1cf ("io_uring: add full-fledged dynamic buffers support")
