## What is CVE-2024-3056? In plain terms

It can be attacked from anywhere on the internet with an ordinary user account, but a person has to take an action first. If it works, the attacker can read data and take it offline.

### The official description

A flaw was found in Podman. This issue may allow an attacker to create a specially crafted container that, when configured to share the same IPC with at least one other container, can create a large number of IPC resources in /dev/shm. The malicious container will continue to exhaust resources until it is out-of-memory (OOM) killed. While the malicious container's cgroup will be removed, the IPC resources it created are not. Those resources are tied to the IPC namespace that will not be removed until all containers using it are stopped, and one non-malicious container is holding the namespace open. The malicious container is restarted, either automatically or by attacker control, repeating the process and increasing the amount of memory consumed. With a container configured to restart always, such as `podman run --restart=always`, this can result in a memory-based denial of service of the system.

### What kind of flaw is it?

- CWE-400: Uncontrolled Resource Consumption

### How an attack on it works

- Where an attacker can be: Anywhere on the internet
- How hard it is to pull off: Hard: conditions must line up
- Login needed first: An ordinary user account
- Does someone have to click: Yes, a person has to take an action
- What an attacker gets: Can read data and take it offline

Severity vector: `CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:N/A:H`
