Vulnerability Details
The official description of CVE-2025-47374 states that the vulnerability is due to memory corruption when accessing freed memory due to concurrent fence deregistration and signal handling. This vulnerability is classified under CWE-416, which is known as use after free.
The CVSS score for this vulnerability is 6.5 which classifies it as medium severity. The attack vector is local, with a high attack complexity and low privileges required. No user interaction is needed, making this vulnerability particularly concerning.
The impacts of this vulnerability are notable; confidentiality impact is low, while both integrity and availability impacts are high. This means that while sensitive information may not be compromised, the integrity and operational capability of the affected systems could be significantly impaired.
Technical Analysis
The root cause of CVE-2025-47374 lies in concurrent processes that lead to memory being accessed after it has been freed. This memory corruption vulnerability is particularly critical in systems where concurrent fence deregistration occurs, allowing attackers to manipulate memory allocations.
The attack vector is local, which means the attacker must have access to the system to exploit the vulnerability. Furthermore, the high attack complexity indicates that the exploitation may require sophisticated techniques or specific conditions to be met.
Low privileges are required for exploitation, allowing potential attackers with minimal access to perform malicious actions. No user interaction is required, which further increases the risk, as it can be exploited without the target's knowledge.
The integrity impact is high, meaning that an attacker could modify data or system settings, while the availability impact is also high, indicating that the system could become inoperable as a result of exploitation.
Risk & Impact Analysis
Organizations using Qualcomm firmware products affected by this vulnerability face significant risks. The potential for memory corruption can lead to unauthorized access, data loss, and system downtime. As such, the blast radius could extend beyond individual systems, potentially affecting networked environments.
The urgency of remediation is underscored by the CVSS score of 6.5, which indicates a medium severity level. Organizations should prioritize patching efforts in their operational cycles to mitigate the risks associated with this vulnerability.
Given the availability impact, organizations must take proactive measures to ensure their systems remain operational. This includes implementing monitoring solutions to detect any signs of exploitation and preparing incident response plans.
