HighCVSS 8.1/10Last modified Oct 18, 2026

Description

A flaw was found in Kata Containers.

This allows them to mount arbitrary container-rootfs paths over sensitive host locations or provision arbitrary content, potentially exposing confidential information or enabling the acceptance of attacker-controlled input.
