CVE-2026-0243 Vulnerability Summary

CVE-2026-0243: A denial of service (DoS) vulnerability in Palo Alto Networks Prisma SD-WAN ION devices enables an unauthenticated attacker in a network adjacent to a Prisma SD-WAN ION device to cause a system disruption by sending a specially crafted IPv6 packet.

Assessing the Risk of CVE-2026-0243

Access Complexity Graph

The exploitability of CVE-2026-0243 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2026-0243

With low attack complexity and no required privileges, CVE-2026-0243 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2026-0243, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis

Below is the Impact Analysis for CVE-2026-0243, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: None
    CVE-2026-0243 has no significant impact on data confidentiality.
  • Integrity: None
    CVE-2026-0243 poses no threat to data integrity.
  • Availability: High
    CVE-2026-0243 can disrupt system operations, potentially causing complete denial of service (DoS).
