CVE-2025-24983 is a high-severity vulnerability that affects several versions of Microsoft Windows, including Windows 10 and Windows Server editions. The vulnerability arises from a 'use after free' condition in the Windows Win32 Kernel Subsystem. Attackers may leverage this vulnerability to elevate privileges locally, which can lead to unauthorized access and control over affected systems.
The CVSS score for this vulnerability is 7.0, indicating a high level of severity. This classification is critical as it highlights the potential for significant impact if exploited. Organizations must take this vulnerability seriously as it allows attackers to gain elevated privileges, which can be used to execute arbitrary code or gain access to sensitive information.
Given the nature of this vulnerability and its potential impact, organizations should prioritize patching immediately. The vulnerability was disclosed on March 11, 2025, and is included in the Known Exploited Vulnerabilities (KEV) catalog, indicating that active exploitation in the wild may be a concern.
Defenders are urged to assess their environments for affected systems and ensure that patches are applied as soon as they are available. Failure to address this vulnerability could leave systems open to exploitation by malicious actors.
Vulnerability Details
The official description of CVE-2025-24983 states: 'Use after free in Windows Win32 Kernel Subsystem allows an authorized attacker to elevate privileges locally.' This vulnerability is classified under CWE-416, which refers to a situation where a program continues to use a pointer after it has been freed.
Affected products include Windows 10 (1507, 1607), Windows Server 2008, 2012, and 2016. The vulnerability has been assigned a CVSS score of 7.0, which signifies high severity. Organizations running these products should take immediate action to mitigate risks associated with this vulnerability.
Technical Analysis
The root cause of CVE-2025-24983 is a use-after-free vulnerability in the Windows Win32 Kernel Subsystem. This flaw allows an attacker with local access to manipulate memory operations, leading to privilege escalation. The attack vector is local, meaning that an attacker needs to have access to the system where the vulnerability exists.
The attack complexity is rated as high, indicating that an attacker must have specific knowledge about the system and the ability to execute particular actions to exploit this vulnerability. Privileges required for exploitation are low, as only standard user privileges are necessary for an attacker to initiate the attack.
User interaction is not required for exploitation, meaning that an attacker can execute the attack without needing the victim to perform any action. The impact on confidentiality, integrity, and availability is high, making this a critical security concern for organizations using the affected versions of Windows.
Risk & Impact Analysis
Organizations running affected versions of Microsoft Windows should understand the real-world risks associated with CVE-2025-24983. The potential blast radius is significant, as this vulnerability can affect multiple systems within an organization's network, allowing attackers to gain elevated privileges and potentially compromise sensitive data.
Risk to organizations includes unauthorized access to sensitive information and the ability to execute arbitrary code. Given the high CVSS score and the inclusion in the KEV catalog, organizations should assess the urgency of remediation based on their specific environment and threat landscape.
Organizations should address this vulnerability in their priority patch cycle to mitigate the associated risks effectively. The longer this vulnerability remains unaddressed, the greater the risk of potential exploitation.
