CVE-2023-2640
Needs a user account on the system (even unprivledged accounts) via overlayfs
Overlayfs allows one, usually read-write, directory tree to be overlaid onto another, read-only directory tree. All modifications go to the upper, writable layer. This type of mechanism is most often used for live CDs but there is a wide variety of other uses.
Or a docker container.
Couldn’t find whether this even impacts LTS builds. Either way, seems like patching should resolve the issue
LTS uses the 5.15 Linux kernel (by default). This vulnerability impacts 6.2.
If I understand correctnly… Ubuntu 22.04.2 LTS has 5.19 kernel by default: https://9to5linux.com/ubuntu-22-04-2-lts-released-with-linux-kernel-5-19-updated-components “the Ubuntu 22.04.2 LTS point release also comes with a newer kernel, namely Linux 5.19, from the Ubuntu 22.10 (Kinetic Kudu) release”
As you said, if it is only 6.2, still out of the window.
Is the end of this headline “because they haven’t updated in 3 years”?
In this case, it’s more like the opposite. People testing the cutting edge versions of Ubuntu are the ones impacted.
Is this an Ubuntu specialty, or other distros are also affected?
