CVE-2025-0815 is classified as a high-severity vulnerability caused by improper input validation. This vulnerability allows for a Denial-of-Service (DoS) condition when malicious ICMPV6 packets are sent to the affected device. The CVSS score of 7.1 indicates that this vulnerability poses a significant risk to organizations. The attack vector is classified as adjacent, meaning attackers need to be on the same network segment as the target device to exploit this flaw.
Organizations should prioritize patching immediately, as the availability impact is rated high. The urgency stems from the potential for service disruption, which could affect business operations. Currently, the vulnerability status is deferred, and it has not been included in the Known Exploited Vulnerabilities (KEV) list, indicating that while it is serious, it may not yet be actively exploited.
The vulnerability was published on February 13, 2025, and has a last modified date of April 15, 2026. Security teams should remain vigilant and monitor for any updates regarding this vulnerability. Despite the lack of confirmed public exploits, the potential impact warrants immediate attention.
To address the potential risks associated with CVE-2025-0815, organizations are encouraged to implement security measures that include regular network monitoring, updating security configurations, and preparing for potential service disruptions.
Vulnerability Details
According to the official description, CVE-2025-0815 is categorized under CWE-20, which pertains to improper input validation. This vulnerability could lead to a Denial-of-Service condition when malicious ICMPV6 packets are sent to the affected device. The current CVSS score is 7.1, categorized as high severity, reflecting the significant risk to availability. The attack vector is classified as adjacent network, with a low attack complexity and no privileges or user interaction required.
The CVE was published on February 13, 2025, with the last modification on April 15, 2026. The absence of public exploit information indicates that there are currently no known public exploits available for this vulnerability.
Technical Analysis
The root cause of CVE-2025-0815 is linked to improper input validation, which fails to adequately filter or validate incoming ICMPV6 packets. This vulnerability can be exploited by attackers who are on the same network as the target device, allowing them to send malicious packets that can cause the device to become unresponsive.
The attack complexity is rated as low, meaning that an attacker with basic skills can execute the attack without significant effort. No privileges are required to exploit this vulnerability, and user interaction is not necessary. The impact on availability is rated high, as successful exploitation can render the device unusable.
Risk & Impact Analysis
Risk to organizations includes potential service disruption due to Denial-of-Service conditions. The availability impact is significant, as attackers could incapacitate devices through malicious ICMPV6 packets. The urgency to address this vulnerability is high, considering its CVSS score of 7.1 and the potential for exploitation.
Organizations must consider the blast radius if this vulnerability is exploited, as it could impact multiple devices on the same network segment. The lack of current known exploits does not diminish the risk, and organizations should remain proactive in their security posture.
The current EPSS score indicates a low likelihood of exploitation, but organizations should not become complacent. The publication and modification dates imply that this vulnerability has been on the radar for some time, warranting attention in security reviews.
