CVE-2026-87679 Vulnerability Summary

CVE-2026-87679: When Brocade Fabric OS versions before 10.0.1 processes trunk configuration operations, the application parses user-supplied list strings into dynamically allocated heap arrays without enforcing boundary checks on the maximum allowable number of elements. An authenticated administrator can exploit this vulnerability via crafted REST API requests containing an excessive number of list delimiters, causing heap corruption that can result in service crash or arbitrary code execution.

Assessing the Risk of CVE-2026-87679

Access Complexity Graph

The exploitability of CVE-2026-87679 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-2026-87679

No exploitability data is available for CVE-2026-87679.

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-2026-87679, 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-2026-87679, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: None
    CVE-2026-87679 does not compromise confidentiality.
  • Integrity: None
    CVE-2026-87679 does not impact data integrity.
  • Availability: None

CAPEC Common Attack Pattern Enumeration and Classification

  • Forced Integer Overflow CAPEC-92 This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.
