CVE-2026-114236 — Podman: goroutine/file-descriptor leak in storage/pkg/archive.applylayer and applyuncompressedlayer on malformed layers

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

1. Identify exposed assets running the affected vendor/product/version combinations (Red Hat Confidential Compute Attestation, Red Hat Developer Hub, Red Hat DPU kit for NVIDIA…).
2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
3. Exploitation requires user interaction: tighten email/web filtering and warn affected users.
4. Search available logs for exploit probes matching the vulnerability class (denial of service), errors and authentication anomalies.

Affected scope

Vendor, product and versions as the sources word them.
