Hi,

FYI, your patch has been queued to stable release 22.11.11

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/29/25. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/059f9f130cb425d9186563ce7e5142ed0554ec56

Thanks.

Luca Boccassi

Subject: [PATCH] net/enetfec: fix out-of-bounds access in UIO mapping

[ upstream commit 22b0837bd93a777b8ca7fcf234985175e456a4f5 ]

NXP internal Coverity flagged a potential out-of-bounds
access due to invalid mapping size. This patch adds a check to
ensure the mapping size is within valid bounds before proceeding
with memory mapping.

Fixes: b84fdd39638b ("net/enetfec: support UIO")
