CI Operators:

RedHat has announced multiple High severity Linux kernel vulnerabilities [1-10] affecting RHEL 7, 8, and 9, including RedHat variants such as Rocky Linux and AlmaLinux. These vulnerabilities can enable a local attacker to gain elevated privileges.



Many of these vulnerabilities are due to issues in the netfilter kernel module. It is possible to prevent the module from loading [11]. However, note that containerized deployments, such as Red Hat OpenShift Container Platform, require the module to be enabled.


Affected Software

Linux Kernel in RHEL 7, 8, 9, including RedHat variants



Update to the latest kernel version for your operating system as soon as possible. If you do not have a containerized deployment, you can mitigate the issue by preventing the appropriate modules from loading.















How Trusted CI can help:

The potential impact of any vulnerability, and therefore the appropriate response, depends in part on operational conditions that are unique to each cyberinfrastructure deployment. Trusted CI cannot provide a one-size-fits-all severity rating and response recommendation for all NSF cyberinfrastructure. Please contact us ( if you need assistance with assessing the potential impact of this vulnerability in your environment and/or you have additional information about this issue that should be shared with the community.
