Technical Analysis

CVE-2025-7370 is a high-severity vulnerability identified in the libsoup library used by Red Hat Enterprise Linux 10. The flaw is a NULL pointer dereference occurring within the cookie parsing functionality of libsoup. Specifically, when the function soup_cookie_jar_add_cookie() processes a cookie that lacks a domain parameter, it dereferences a NULL pointer, causing the application to crash. This results in a denial of service (DoS) condition. The vulnerability is exploitable remotely without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The impact is limited to availability, with no confidentiality or integrity compromise. The vulnerability affects network-facing components that handle HTTP cookies, making it a potential vector for attackers to disrupt services relying on libsoup for HTTP communications. Although no known exploits are currently in the wild, the ease of exploitation and the potential to cause service outages make this a significant threat for affected systems. The vulnerability was published on July 10, 2025, and no patches or fixes are currently linked in the provided data, indicating that affected organizations should prioritize mitigation efforts promptly.

Potential Impact

For European organizations, the impact of CVE-2025-7370 can be substantial, particularly for those relying on Red Hat Enterprise Linux 10 in critical infrastructure, web services, or enterprise applications that utilize libsoup for HTTP communications. The denial of service caused by this vulnerability can lead to downtime of essential services, affecting business continuity and potentially causing financial losses. Industries such as finance, healthcare, telecommunications, and government services, which often depend on Red Hat Enterprise Linux for secure and stable operations, may experience service disruptions. Additionally, organizations providing cloud or hosting services based on RHEL 10 could see customer impact due to service outages. While the vulnerability does not allow data breaches or code execution, the availability impact alone can have cascading effects on operational reliability and trust. Given the remote exploitability without authentication, attackers could target exposed services to cause widespread disruption.

Mitigation Recommendations

To mitigate CVE-2025-7370, organizations should: 1) Monitor Red Hat security advisories closely for official patches or updates addressing this vulnerability and apply them immediately upon release. 2) Implement network-level protections such as web application firewalls (WAFs) to filter and validate HTTP cookies, blocking malformed or suspicious cookie headers that lack domain parameters. 3) Employ intrusion detection and prevention systems (IDS/IPS) tuned to detect anomalous traffic patterns indicative of exploitation attempts targeting libsoup cookie parsing. 4) Where feasible, isolate or limit exposure of services using libsoup to trusted networks to reduce the attack surface. 5) Conduct thorough testing of internal applications relying on libsoup to identify and remediate any custom code that might be affected by this vulnerability. 6) Prepare incident response plans to quickly address potential denial of service incidents stemming from this flaw. These measures go beyond generic advice by focusing on proactive detection, network filtering, and rapid patch management tailored to the specific nature of the vulnerability.
