It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-25506 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-25506/ (Markdown: https://insights.sbomify.com/CVE-2026-25506/index.md)","id":"CVE-2026-25506","markdown":"https://insights.sbomify.com/CVE-2026-25506/index.md","name":"CVE-2026-25506","record":{"aliases":["ALSA-2026:3032","ALSA-2026:3033","ALSA-2026:3034","AZL-77444","AZL-77451","CLSA-2026-1772571803","CLSA-2026-1772572505","DEBIAN-CVE-2026-25506","DLA-4477-1","DSA-6129-1","GHSA-r9cr-jf4v-75gh","OESA-2026-1348","RHSA-2026:2918","RHSA-2026:2923","RHSA-2026:2934","RHSA-2026:2949","RHSA-2026:2954","RHSA-2026:3010","RHSA-2026:3011","RHSA-2026:3012","RHSA-2026:3013","RHSA-2026:3032","RHSA-2026:3033","RHSA-2026:3034","RLSA-2026:3032","RLSA-2026:3033","RLSA-2026:3034","SUSE-SU-2026:0448-1","SUSE-SU-2026:0450-1","SUSE-SU-2026:0451-1","SUSE-SU-2026:0484-1","UBUNTU-CVE-2026-25506","USN-8040-1","openSUSE-SU-2026:10178-1"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["privilege_escalation","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"MUNGE authentication service","requires_auth":"low_privilege","summary":"Local attackers can exploit a buffer overflow in MUNGE to leak keys and forge credentials, enabling impersonation of any user including root.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"munge","vendor":"opensuse"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"},{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"MUNGE is an authentication service for creating and validating user credentials. From 0.5 to 0.5.17, local attacker can exploit a buffer overflow vulnerability in munged (the MUNGE authentication daemon) to leak cryptographic key material from process memory. With the leaked key material, the attacker could forge arbitrary MUNGE credentials to impersonate any user (including root) to services that rely on MUNGE for authentication. The vulnerability allows a buffer overflow by sending a crafted message with an oversized address length field, corrupting munged's internal state and enabling extraction of the MAC subkey used for credential verification.
