CVE-2025-60019 identifies a NULL pointer dereference vulnerability in the OpenSSL backend of glib-networking version 2.60. The root cause is the failure to properly check the return value of memory allocation routines, which can lead to dereferencing a NULL pointer when an out-of-memory condition occurs. This flaw can cause the affected application or service to crash, resulting in a denial of service (DoS) condition. The vulnerability does not allow for unauthorized access, data leakage, or code execution, as it only impacts availability. The CVSS v3.1 score is 3.7 (low), reflecting the network attack vector but high attack complexity and no privileges or user interaction required. There are no known exploits in the wild, and no patches have been linked yet, indicating that this is a recently disclosed issue. The vulnerability affects glib-networking 2.60, a library commonly used in Linux environments to provide network-related functionality, including SSL/TLS support via OpenSSL. The issue is technical in nature, involving improper error handling in memory allocation, which is a common programming oversight but can have operational consequences if triggered.

For European organizations, the primary impact of CVE-2025-60019 is potential service disruption due to application crashes caused by NULL pointer dereference. This could affect network services or applications relying on glib-networking with OpenSSL, especially in server environments or embedded systems. Although the vulnerability does not compromise data confidentiality or integrity, availability interruptions could affect critical services, leading to operational downtime and potential business impact. Organizations with high availability requirements or those running critical infrastructure on Linux systems using glib-networking may face increased risk. However, the high attack complexity and lack of known exploits reduce the immediate threat level. Still, unpatched systems remain vulnerable to denial of service attacks that could be leveraged in targeted disruption campaigns.

To mitigate CVE-2025-60019, organizations should monitor vendor advisories for patches or updates to glib-networking addressing this issue and apply them promptly. In the absence of official patches, consider recompiling glib-networking with additional error checking or memory allocation safeguards if feasible. Implement resource monitoring and limits to reduce the likelihood of out-of-memory conditions that trigger the vulnerability. Employ robust system and application-level monitoring to detect crashes or abnormal terminations related to this issue. For critical systems, consider isolating affected services or using alternative libraries until a fix is available. Regularly update and audit software dependencies to minimize exposure to similar vulnerabilities. Additionally, ensure that incident response plans include procedures for handling denial of service events caused by software faults.
