PSA: Update your docker installation. Leaky Vessels flaws allow hackers to escape Docker, runc containers
bleepingcomputer.com
Snyk team has found four vulnerabilities collectively called "Leaky Vessels" that impact the runc and Buildkit container infrastructure and build tools, potentially allowing attackers to perform container escape on various software products.
On January 31, 2024, Buildkit fixed the flaws with version 0.12.5, and runc addressed the security issue impacting it on version 1.1.12.
Docker released version 4.27.0 on the same day, incorporating the secured versions of the components in its Moby engine, with versions 25.0.1 and 24.0.8.

I believe podman and containerd use
runcunder the hood so they're also affected by this container escape vulnerability. You should update it to the latest version.Podman can use different tools under the hood, will check which one I am using.
I think on redhat/fedora it uses runc by default and on debian/arch it uses crun by default.
