High CVSS 8.1

CVE-2026-77176

NVD analysis in progress

A flaw was found in Kata Containers. In configurations utilizing genpolicy for Confidential Containers guest protection, a malicious host operator can exploit insufficient validation of CreateContainer mount and storage rules. 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.

What this means

Exposure
Exploitable remotely over the network, with an ordinary user account and with no action from the victim.
Impact
An attacker can read sensitive data and modify or destroy data.
Weakness
The attacker controls the name or path of a file the application operates on.
Likelihood
Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.

What to doFold into the next patch cycle.
