CVE-2021-33909

Post by kilian » 2021/07/21 14:51:09

Hi!

I see that the kernel fix for CVE-2021-33909 (kernel-3.10.0-1160.36.2.el7, https://access.redhat.com/errata/RHSA-2021:2725) is not available in CentOS updates yet. What's the typical delay for inclusion in CentOS?

Thanks.

I guess it depends on size of build and severity.

If we look at the previous kernel release, 3.10.0-1160.31.1.el7
* 2021-06-08 RHEL annoucement https://access.redhat.com/errata/RHSA-2021:2314
* 2021-06-14 CentOS release https://lists.centos.org/pipermail/cent ... 48337.html

It's building and likely to be released today/tomorrow.

Is there a status page on the build progress?

I am running CentOS 7.6 1810 and I referred to :

https://lists.centos.org/pipermail/cent ... 48344.html
and
http://mirror.centos.org/centos/7/updat ... s/?C=M;O=D
to download:
bpftool-3.10.0-1160.36.2.el7.x86_64.rpm
kernel-3.10.0-1160.36.2.el7.x86_64.rpm
kernel-abi-whitelists-3.10.0-1160.36.2.el7.noarch.rpm
kernel-debug-3.10.0-1160.36.2.el7.x86_64.rpm
kernel-debug-devel-3.10.0-1160.36.2.el7.x86_64.rpm
kernel-devel-3.10.0-1160.36.2.el7.x86_64.rpm
kernel-doc-3.10.0-1160.36.2.el7.noarch.rpm
kernel-headers-3.10.0-1160.36.2.el7.x86_64.rpm
kernel-tools-3.10.0-1160.36.2.el7.x86_64.rpm
kernel-tools-libs-3.10.0-1160.36.2.el7.x86_64.rpm
kernel-tools-libs-devel-3.10.0-1160.36.2.el7.x86_64.rpm
perf-3.10.0-1160.36.2.el7.x86_64.rpm
python-perf-3.10.0-1160.36.2.el7.x86_64.rpm

Probably you also need:
linux-firmware 20200421-80.git78c0348.el7_9

to put all together into a folder and go to that folder to apply all rpm via: yes | yum --disablerepo=\* update ./*.rpm ;

It works! no vulnerability to my system now.

Good luck

Do not do this.Only 7.9 gets any support. By running 7.6 you are missing out on nearly 3 years of security patches.
