Description

This security bulletin contains information about 2 vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2026-47262)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in group parsing when creating a container from a maliciously crafted image. A remote user can supply a specially crafted image to cause a denial of service.

Successful exploitation can exhaust memory and trigger an out-of-memory kill of the containerd process, making the runtime API unavailable.


2) Input validation error (CVE-ID: CVE-2026-53488)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary commands on the host.

The vulnerability exists due to improper input validation in the containerd CRI plugin when propagating image configuration labels to containers. A remote attacker can supply a crafted image with malicious labels to execute arbitrary commands on the host.

Exploitation requires a plugin that consumes container labels for some operations.
