Hi all,

CIP kernel team has released Linux kernel 4.19.50-cip3 and 4.4.181-cip33.
You can get this release via the git tree at:


branch: linux-4.19.y-cip
commit: 0f13d9b4d0efa9e87381717c113df57718bc92d6


branch: linux-4.4.y-cip
commit: b791a4823f245e7871dbdd05d8f13bcc5dc377c9

And I introduce the updates for each kernel below.

About 4.19.50-cip3:
* This version has been updated from stable version 4.19.13 to 4.19.50,
many CVE fixes including MDS (Microarchitectural Data Sampling:
CVE-2018-12126, CVE-2018-12127,, CVE-2019-11091).
* CIP updates include device-tree fixes by Renesas.

About 4.4.176-cip32:
* This version has been updated from stable version 4.4.176 to 4.4.181,
this also includes MDS fixes as in 4.19.y.
* CIP updates include update of RZ/G1C by Renesas.
I forgot to explain about MDS.

Although patches for MDS are included in this release, no test code has been
published for these, so we have not tested for MDS. Also, patches did not
really follow the stable rules, so they could not be checked the same way
as checking for other patches. But the bug is ugly enough so we included
the patches anyway.
For the above reasons, modern x86 CPUs can not really be trusted with secrets;
similar attacks are likely to happen in future.
