Summary
CVE-2025-24050 is a high-severity Heap-based Buffer Overflow (CWE-122) vulnerability in Microsoft Windows 11 24H2. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 35.4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-16 (Memory Protection) and SI-2 (Flaw Remediation).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates the heap-based buffer overflow by requiring timely application of vendor patches for the Hyper-V vulnerability.
Implements memory protection mechanisms such as DEP and ASLR that prevent exploitation of heap-based buffer overflows in Hyper-V.
Enforces least privilege to restrict the initial low-privilege access required by the attacker and limit damage from successful escalation.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Heap-based buffer overflow in Hyper-V hypervisor directly enables local privilege escalation from low-privileged access on the host.
NVD Description
Heap-based buffer overflow in Role: Windows Hyper-V allows an authorized attacker to elevate privileges locally.
Deeper analysisAI
CVE-2025-24050 is a heap-based buffer overflow vulnerability (CWE-122, CWE-125) in the Windows Hyper-V role. It affects the Hyper-V hypervisor component on Windows systems. Published on 2025-03-11T17:16:27.273, the vulnerability has a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high impact potential.
A local attacker with low privileges (PR:L) can exploit this vulnerability through low-complexity attacks (AC:L) requiring no user interaction (UI:N). Successful exploitation enables privilege escalation on the host system, granting high confidentiality, integrity, and availability impacts (C:H/I:H/A:H).
