Answer in brief
CVE-2024-6387 records a High severity (CVSS 8.1) vulnerability in Openssh: regresshion - race condition in ssh allows rce/dos. The current sources do not mark it as known exploited. The current feed maps Siemens/Industrial Edge Management OS (IEM-OS) (generic), Red Hat/openshift/ose-rhel-coreos-8 (generic), OpenSSH (generic), Siemens/SIMATIC S7-1500 CPU 1518-4 PN/DP MFP (generic) and additional mapped packages. Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 8.1. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.
