Protect Your Linux Systems from 6 Exploitable Flaws
Why This Update Demands Immediate Attention
Did you know 43% of cloud breaches exploit unpatched vulnerabilities? This SUSE-issued critical update addresses six high-risk security flaws in rust-keylime – a cornerstone of secure cloud attestation frameworks. Left unpatched, these vulnerabilities expose SUSE Linux Enterprise Micro 5.4 environments to:
Remote code execution (CVE-2025-58266)
Memory exhaustion attacks (CVE-2024-43806)
Service disruption via infinite loops (CVE-2024-32650)
Vulnerability Breakdown: Severity & Impact
(CVSS Scores from SUSE/NVD)
| CVE ID | Risk Level | CVSS Score | Primary Threat |
|---|---|---|---|
| CVE-2025-58266 | Critical | 4.7 (SUSE) | Command injection via shlex |
| CVE-2023-26964 | High | 7.5 (NVD) | HTTP/2 stream stacking RCE |
| CVE-2024-32650 | High | 7.5 (SUSE) | Rustls infinite loop DoS |
| CVE-2024-43806 | Medium | 6.5 (SUSE) | Memory explosion in rustix directory ops |
Technical Insight: The CVE-2025-58266 command injection flaw stems from improper input sanitization in quote handling – a reminder that even memory-safe languages like Rust inherit risks from dependency chains.

FAQ: rust-keylime Security Update
Q: Is downtime required for patching?
A: Yes – restart keylime services post-update. Schedule maintenance windows accordingly.
Q: Can exploits bypass Kubernetes security?
A: CVE-2024-43806 could affect container hosts. Isolate affected nodes before patching.
Q: Are workarounds available?
A: SUSE recommends full patch application. Temporary mitigation: disable non-essential keylime agents.
