SUSE has released an urgent security update for helm-mirror, addressing two critical vulnerabilities (CVE-2025-32386 & CVE-2025-32387) that could lead to denial-of-service (DoS) attacks and stack overflow exploits. 

Enterprises using Kubernetes, container orchestration, or DevOps pipelines must apply this patch immediately to prevent system instability.

Vulnerability Breakdown & Risk Assessment

1. CVE-2025-32386 – Memory Exhaustion Attack

• CVSS 4.0 Score: 6.9 (Moderate-High)

• Impact: Attackers can craft malicious Helm charts to consume excessive memory, crashing the service.

• Affected Products:

  • SUSE Linux Enterprise Server 15 SP6

  • openSUSE Leap 15.6

  • Containers Module 15-SP6

2. CVE-2025-32387 – Stack Overflow Exploit

• CVSS 4.0 Score: 6.9 (Moderate-High)

• Impact: Deep recursion in chart parsing can exceed stack limits, leading to crashes.

• Affected Products: Same as above.

🔴 Why This Matters for Enterprises:

• Kubernetes security relies on Helm for deployments—unpatched systems risk downtime & breaches.

• DevOps teams must prioritize updates to maintain CI/CD pipeline integrity.
