Description

This security bulletin contains information about 1 vulnerability.


1) Input validation error (CVE-ID: CVE-2026-17113)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 6.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local privileged user to cause a denial of service.

The vulnerability exists due to improper input validation in CRI-O daemon when processing a crafted OCI image with a malformed environment variable entry. A local privileged user can supply a specially crafted OCI image to cause a denial of service.

This only occurs when no environment variables are set in the container spec, and the normal Kubernetes API path does not trigger the issue.
