"According to its self-reported version, the remote device is running Wind River VxWorks 7. Releases 24.03 through
26.03 are affected by a denial of service vulnerability:

  - In Wind River VxWorks 7 24.03 through 26.03, a memory leak occurs under specific, non-default configuration states
    when processing specific service routines, causing the system to terminate operations before releasing allocated
    memory pools. (CVE-2026-102005)

Note that Nessus cannot determine the VxWorks 7 release designation (for example 26.03) from the detected operating
system version, and cannot confirm the non-default configuration required for exploitation. This finding is therefore
reported as a potential vulnerability.

Note that Nessus has not tested for this issue but has instead relied only on the OS version.");
