Noroxi assessment
Priority: This week (action score 62/100)
- CISA has confirmed exploitation in the wild (Mar 4, 2025). Remediation deadline for US federal agencies: Mar 25, 2025.
- Probability of exploitation in the next 30 days: 1.5% (FIRST EPSS); higher than 75.5% of all records.
- Someone with local access to the system can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Don’t wait for the next maintenance window. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS
VMware ESXi, and Workstation contain a TOCTOU (Time-of-Check Time-of-Use) vulnerability that leads to an out-of-bounds write. A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host.
