  • CVE-2024-21407: Windows Hyper-V Remote Code Execution vulnerability,  CVEv3 Score 8.1, critical; To successfully exploit this vulnerability, an attacker must be authenticated and gather information about the target environment to plan their attack. The complexity of the attack is high, but exploitation could lead to code execution on the host server.
  • CVE-2024-21433: Windows Print Spooler Elevation of Privilege vulnerability,  CVEv3 Score 7.0, important; This vulnerability is classified as "Exploitation More Likely" and has been assigned a CVSSv3 score of 7.0. Exploitation of this vulnerability would require an attacker to gain a race condition that could grant the attacker SYSTEM privileges.
  • CVE-2024-21433: Windows Print Spooler Elevation of Privilege vulnerability,  CVEv3 Score 7.0, important; This vulnerability is classified as "Exploitation More Likely" and has been assigned a CVSSv3 score of 7.0. Exploitation of this vulnerability would require an attacker to gain a race condition that could grant the attacker SYSTEM privileges.
  • CVE-2024-21443, CVE-2024-26173, CVE-2024-26176, CVE-2024-26178, CVE-2024-26182: Windows Kernel Elevation of Privilege vulnerability, CVEv3 Score 7.8 (CVE-2024-21443 with CVEv3 7.3), important; CVE-2024-26182 is the only Windows Kernel EoP vulnerability that has been classified as "Exploitation More Likely".
