Two Linux vulnerabilities introduced recently into the Ubuntu kernel create the potential for unprivileged local users to gain elevated privileges on a massive number of devices.

    CVE-2023-2640 and CVE-2023-32629 if you don’t fancy spending an age clicking Object to all the ‘legitimate interest’ cookie shit.

      Tip: “I still don’t care about cookies” for desktop browsers + deleting all cookies at the end of the browser session works flawlessly for me.

    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.

    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.

    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 this an Ubuntu specialty, or other distros are also affected?

      They are specific to the kernels delivered with Ubuntu because of changes introduced by Canonical in OverlayFS:

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
