I think we have a few CentOS users on this list, so this may be a bit alarming:

https://www.neowin.net/news/google-discloses-centos-linux-kernel-vulnerabilities-following-failure-to-issue-timely-fixes/

Here are a couple of the important chunks:

"As detailed in the technical document here, Google Project Zero's
security researcher Jann Horn learned that kernel fixes made to stable
trees are not backported to many enterprise versions of Linux. To
validate this hypothesis, Horn compared the CentOS Stream 9 kernel to
the stable linux-5.15.y stable tree. For those unaware, CentOS is a
Linux distro closest to Red Hat Enterprise Linux (RHEL) and its
version 9 is based on the linux-5.14 release."

"As expected, it turned out that several kernel fixes have not been
made deployed in older, but supported versions of CentOS Stream/RHEL.
Horn further noted that for this case, Project Zero is giving a 90-day
deadline to release a fix, but in the future, it may allot even
stricter deadlines for missing backports ..."
