CVE-2026-95838 is a vulnerability in containerd, an industry-standard container runtime. Prior to versions 1.7.35, 2.0.12, 2.2.8, and 2.3.5, the layer unpack handler could be exploited by a malicious image layer that triggers repeated directory traversals during opaque whiteout processing. This can cause high CPU usage, delay container startup, and reduce image-pull concurrency for unrelated deployments. The issue is fixed in the specified versions.
