Published: 14 January 2026
Summary
CVE-2025-12050 is a high-severity Out-of-bounds Write (CWE-787) vulnerability in Insyde (inferred from references). 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 0.9th 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-10 (Information Input Validation) and SI-16 (Memory Protection).
Deeper analysis
CVE-2025-12050 is a buffer overflow vulnerability (CWE-787) with 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), published on 2026-01-14. It affects drivers in tool packages from Insyde that use the RTL_QUERY_REGISTRY_DIRECT flag to read registry values. An untrusted user-mode application can influence these registry values, triggering the buffer overflow during the read operation.
A local attacker with low privileges can exploit this vulnerability with low attack complexity and no user interaction required. Exploitation involves crafting a malicious registry value accessible via local access, leading to a buffer overflow in the driver. Successful attacks can achieve high impacts on confidentiality, integrity, and availability, potentially enabling arbitrary code execution, data corruption, or denial of service within the affected driver context.
Insyde's security advisory SA-2025010 provides details on mitigation and patches, available at https://www.insyde.com/security-pledge/sa-2025010/. Security practitioners should consult this advisory for vendor-specific remediation steps, such as applying updated tool packages or disabling affected drivers where feasible.
