High (8.4) in red hat red hat hardened images.
A flaw was found in dnf5daemon-server. Unauthenticated D-Bus methods pass caller-controlled URL or .rpm path patterns into a root-privileged cmdline package loader that may store fetched content in a world-readable cache without size limits, or open local paths as root, allowing a local attacker to disclose privileged content and to deny service via disk exhaustion.

If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2026-123177 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.Opens a third-party assistant; its answer is its own, not cve.bz's.
