Memory corruption while passing pages to DSP with an unaligned starting address
Description
Memory corruption while passing pages to DSP with an unaligned starting address
Remediation
Apply vendor security updates immediately. Monitor for exploitation attempts and review access logs.
Executive Summary:
A high-severity memory corruption vulnerability, identified as CVE-2025-47387, has been discovered in multiple products from the vendor 'Memory'. This flaw can be triggered when the software processes specially crafted JPEG image data, potentially allowing an attacker to crash the system or execute arbitrary code, leading to a full system compromise.
Vulnerability Details
CVE-ID: CVE-2025-47387
Affected Software: Memory Multiple Products
Affected Versions: See vendor advisory for specific affected versions
Vulnerability: This vulnerability is a memory corruption flaw that occurs within a driver or component responsible for processing Input/Output Control (IOCTL) calls. When a specially crafted JPEG data stream is sent via an IOCTL request, the software fails to properly validate the data's size or structure. This lack of verification allows an attacker to write data outside of the intended memory buffer, leading to a heap or stack-based buffer overflow. An attacker with local access could exploit this flaw by crafting a malicious JPEG file and using a program to send it to the vulnerable IOCTL handler, potentially resulting in privilege escalation or arbitrary code execution in the context of the kernel.
Business Impact
This vulnerability is rated as High severity with a CVSS score of 7.8. Successful exploitation could have a significant business impact, including a complete loss of confidentiality, integrity, and availability of the affected system. An attacker who gains kernel-level code execution can bypass all security controls, install persistent malware like rootkits, exfiltrate sensitive company data, or use the compromised system to pivot to other parts of the network. The resulting denial of service from a system crash could also disrupt critical business operations.
Remediation Plan
Immediate Action: Apply the security updates released by the vendor, 'Memory', across all affected systems without delay. Concurrently, security teams should actively monitor for any signs of exploitation attempts and conduct a thorough review of relevant system and application access logs for anomalous activity targeting the affected components.
Proactive Monitoring: Implement enhanced monitoring on endpoints with the vulnerable software. Security teams should look for unusual or malformed IOCTL requests related to JPEG processing, unexpected system crashes (BSOD/kernel panics), and any logs from security tools (e.g., EDR) indicating memory access violations or suspicious process behavior originating from applications that handle image data.
Compensating Controls: If immediate patching is not feasible, implement compensating controls to reduce the risk. Restrict user and application permissions to limit access to the vulnerable driver or API. Utilize application whitelisting or control solutions to prevent unauthorized software from running and attempting to trigger the vulnerability. Ensure Host-based Intrusion Prevention Systems (HIPS) are enabled and configured to detect and block buffer overflow exploitation techniques.
Exploitation Status
Public Exploit Available: false
Analyst Notes: As of the publication date, December 18, 2025, there are no known public proof-of-concept exploits, and the vulnerability is not listed on the CISA Known Exploited Vulnerabilities (KEV) catalog. However, memory corruption vulnerabilities are frequently targeted by threat actors for developing privilege escalation exploits. Organizations should assume that an exploit could be developed and weaponized in the near future.
Analyst Recommendation
Given the high severity (CVSS 7.8) and the potential for complete system compromise via privilege escalation, it is strongly recommended that organizations prioritize the deployment of the vendor-supplied patches for CVE-2025-47387. Although there is no evidence of active exploitation at this time, the nature of the vulnerability makes it an attractive target. The provided remediation and monitoring steps should be implemented immediately to mitigate risk and ensure the security of affected assets.
