CVE-2025-20650 in MT2737
Summary
by MITRE • 03/03/2025
In da, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege, if an attacker has physical access to the device, with no additional execution privileges needed. User interaction is needed for exploitation. Patch ID: ALPS09291294; Issue ID: MSV-2061.

The vulnerability identified as CVE-2025-20650 resides within the da component of a system, representing a critical out-of-bounds write flaw that stems from inadequate input validation mechanisms. This particular weakness manifests as a missing bounds check during data processing operations, creating a scenario where malicious actors can manipulate memory structures beyond their intended boundaries. The vulnerability's classification aligns with CWE-787, which specifically addresses out-of-bounds write conditions that occur when an application writes data past the end of a buffer or array, potentially corrupting adjacent memory locations.
The operational impact of this vulnerability extends significantly when considering the attack vector and privilege requirements. While the flaw necessitates physical access to the target device, it represents a particularly concerning threat because it enables local privilege escalation without requiring any additional execution privileges from the attacker. This characteristic places the vulnerability within the ATT&CK framework under T1068, which covers local privilege escalation techniques, making it a serious concern for environments where physical security controls may be insufficient. The requirement for user interaction during exploitation indicates that social engineering or physical access methods could be employed to trigger the vulnerability, potentially through malicious USB devices or direct manipulation of system interfaces.
The patch identified as ALPS09291294 addresses this vulnerability by implementing proper bounds checking mechanisms within the da component's memory management routines. This fix likely involves adding validation checks before any write operations to ensure that data access remains within predefined buffer limits, thereby preventing the out-of-bounds memory corruption that could otherwise lead to privilege escalation. The issue ID MSV-2061 suggests this vulnerability was tracked through a Microsoft-specific vulnerability management system, indicating the severity and potential impact within enterprise environments where such systems are commonly deployed. Organizations should prioritize immediate deployment of this patch across all affected systems, particularly those with physical access controls that may be susceptible to malicious manipulation. The vulnerability's nature suggests that attackers could potentially leverage this flaw to execute arbitrary code with elevated privileges, making it a critical target for remediation efforts.
The broader implications of this vulnerability extend beyond simple privilege escalation, as it demonstrates the importance of robust input validation and memory safety mechanisms in system components that handle user data or device interactions. System administrators and security teams should conduct comprehensive assessments of their physical security controls and review all components that may be susceptible to similar out-of-bounds write conditions. The presence of such vulnerabilities in core system components underscores the necessity for continuous security auditing and the implementation of secure coding practices that prevent buffer overflow conditions and related memory corruption issues.
