CVE-2026-47218

runwasi facilitates running Wasm and WASI workloads managed by containerd. Prior to 0.6.1, containerd-shim-wasmtime-v1 can treat Wasmtime precompiled bytes supplied directly in an OCI image layer as a trusted artifact from the precompile-cache path and deserialize them as native code. An attacker...

CVE-2026-47218

The runwasi project contains a vulnerability in containerd-shim-wasmtime-v1 prior to version 0.6.1 . The flaw allows an attacker to provide Wasmtime precompiled bytes directly within an OCI image layer, which the shim incorrectly treats as a trusted artifact from the precompile-cache path. By des...

Astra Linux – Vulnerability in containerd-app

Containerd is an open-source container runtime. A bug was discovered in Containerd prior to versions 1.6.38, 1.7.27, and 2.0.4. In these versions, containers launched with a User set as UID:GID that exceeded the maximum 32-bit signed integer could cause an overflow condition, resulting in the...

Astra Linux – Vulnerability in Containerd

Containerd is an open-source container runtime that emphasizes simplicity, robustness, and portability. A bug was discovered in Containerd where container root directories and certain plugins had insufficiently restricted permissions, allowing unprivileged Linux users to access the contents of...

Astra Linux – Vulnerability in Containerd

Containerd is an open-source container runtime. Prior to versions 1.6.18 and 1.5.18, when importing an OCI image, there was no limit on the number of bytes read for certain files. A maliciously crafted image with a large file where no limit was applied could cause a denial of service. This bug ha...

Astra Linux – Vulnerability in Containerd

Containerd is an open-source container runtime. A bug was discovered in Containerd prior to versions 1.6.18 and 1.5.18, where supplementary groups were not set up properly within a container. If an attacker has direct access to a container and manipulates the supplementary group permissions, they...
