Urgent Go 1.23 Security Patch: Critical Vulnerabilities Patched (CVE-2025-47906 & CVE-2025-47907)

 

Critical Go 1.23 security update patches CVE-2025-47906 (path hijacking) & CVE-2025-47907 (data corruption). Install now on SUSE Linux, openSUSE, and SAP systems to prevent exploits. Patch commands included.

Why This Update Demands Immediate Attention

Two critical CVEs threaten Go 1.23 environments across SUSE’s enterprise ecosystem. Attackers could exploit these to:

• Hijack execution paths (CVE-2025-47906, CVSS 4.0)

• Corrupt database scan results (CVE-2025-47907, CVSS 7.0 NVD)
  With 30+ affected products—including SUSE Linux Enterprise Server, SAP Applications, and High-Performance Computing (HPC) clusters—delaying patching risks compliance breaches and system compromise.
