mkfifo\n\n> **CVSS Score:** 7.1\n> **Published:** 2026-07-06\n> **Full Report:** https://cvereports.com/reports/CVE-2026-35341\n\n## Summary\nCVE-2026-35341 is a high-severity vulnerability in the mkfifo utility of uutils coreutils, involving a logic-flow bypass and a TOCTOU race condition that permits unauthorized file permission degradation and privilege escalation.\n\n## TL;DR\nA logical flow-control bypass and a TOCTOU race condition in the uutils coreutils mkfifo utility allow unprivileged local attackers to degrade system file permissions and escalate privileges.\n\n## Exploit Status: POC\n\n## Technical Details\n\n- **CWE ID**: CWE-732\n- **Attack Vector**: Local (AV:L)\n- **CVSS v3.1 Score**: 7.1\n- **EPSS Score**: 0.00165\n- **Exploit Status**: Proof of Concept (PoC) Available\n- **CISA KEV Status**: Not Listed\n\n## Affected Systems\n\n- uutils coreutils\n- Wolfi developer images\n- Chainguard developer images\n- Debian Linux (experimental uutils-coreutils package)\n- Ubuntu Linux (experimental uutils-coreutils package)\n- **coreutils**: < commit pull/10376 (Fixed in: `PR #10376 merged version`)\n\n## Mitigation\n\n- Upgrade uutils coreutils to a release incorporating Pull Request #10376.\n- Enable system-wide symlink protections via sysctl configuration.\n- Avoid executing mkfifo with elevated privileges in globally writable directories.\n\n**Remediation Steps:**\n1. Identify all system deployments using uutils coreutils instead of GNU coreutils.\n2. Recompile or update uutils coreutils packages to versions beyond the commit in PR #10376.\n3. Add 'fs.protected_symlinks = 1' to /etc/sysctl.conf and run 'sysctl -p' to apply protections.\n4. Audit existing critical file permissions to identify unauthorized modifications.\n\n## References\n\n- [uutils coreutils Issue #10020: mkfifo TOCTOU and logic flow permissions bypass](https://github.com/uutils/coreutils/issues/10020)\n- [uutils coreutils Pull Request #10376: mkfifo fix permissions update on creation failure](https://github.com/uutils/coreutils/pull/10376)\n- [Official CVE-2026-35341 Record on CVE.org](https://www.cve.org/CVERecord?id=CVE-2026-35341)\n- [Wiz Vulnerability Database Overview for CVE-2026-35341](https://www.wiz.io/vulnerability-database/cve/cve-2026-35341)\n\n\n---\n*Generated by [CVEReports](https://cvereports.com/reports/CVE-2026-35341) - Automated Vulnerability Intelligence*", "url": "https://gist.github.com/alon710/d7b15b70ec7c7ecc30109bf6cff7b4d3"}, {"timestamp": "2026-10-17T09:40:53Z", "date_only": false, "value": "2026-10-17T09:40:53Z", "kind": "other", "label": "Updated", "source": "osv_ubuntu \u00b7 UBUNTU-CVE-2026-35341", "record": "UBUNTU-CVE-2026-35341", "field": "modified"}, {"timestamp": "2026-10-26T22:10:00.163Z", "date_only": false, "value": "2026-10-26T22:10:00.163", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-35341", "record": "FKIE_CVE-2026-35341", "field": "lastModified"}], "metrics": {"as_of": "2026-10-28T18:38:29.481Z", "anchors": {"origin": {"timestamp": "2026-04-22T16:07:39.221Z", "date_only": false, "value": "2026-04-22T16:07:39.221Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-35341", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-04-22T16:07:39.221Z", "date_only": false, "value": "2026-04-22T16:07:39.221Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-35341", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "exploit_publication": null, "exploitation": null, "patch": null}, "vendor_response_time": {"available": false, "missing": ["start", "end"]}, "time_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit_publication": {"available": false, "missing": ["end"]}, "time_to_patch": {"available": false, "missing": ["start", "end"]}, "total_time_to_patch": {"available": false, "missing": ["start", "end"]}, "disclosure_to_patch": {"available": false, "missing": ["end"]}, "time_unpatched": {"available": true, "seconds": 16338650.260665, "hours": 4538.513961295833, "days": 189.1047483873264, "min_seconds": 16338650.260665, "max_seconds": 16338650.260665, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-04-22T16:07:39.221Z", "date_only": false, "value": "2026-04-22T16:07:39.221Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-35341", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-10-28T18:38:29.481Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
