Technical details

A resource leak in the IPNET subsystem fails to release allocated kernel memory and file descriptors when specific system call arguments cause the calling application to terminate. The vulnerability is triggered via crafted system call arguments without requiring authentication or user interaction. An attacker can exhaust system resources (memory and file descriptors) leading to denial of service. The vulnerability was fixed in VxWorks 7 version 26.09.
