Two potential signed to unsigned conversion errors and buffer overflow vulnerabilities at the following locations in the Zephyr IPM drivers.
CVE-2023-5184
This high-severity CVE scores 7.0 under NVD CVSS v3. EPSS exploit probability: 0.3%, top 50% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
