This security bulletin contains information about 1 vulnerability.


1) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-53493)

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

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


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

The vulnerability exists due to allocation of resources without limits or throttling in the image pull handlers when recursively traversing crafted OCI image index descriptor graphs. A remote attacker can provide a crafted OCI image index with deeply nested or heavily fanned-out descriptors to cause a denial of service.

The issue occurs during image pulling, before container execution.
