CVE-2026-97686

Kernel resource leak via IPNET syscall cleanup failure

Published Sep 28, 2026 · Updated Sep 28, 2026

Resource leak in Wind River VxWorks 7 before 26.09 allows local users to retain kernel memory and file descriptors via crafted system call arguments. The IPNET subsystem fails to release those resources when specific arguments cause the calling application to terminate. Triggering requires code execution on the VxWorks target; the supplied advisory does not establish a network-only trigger or a resulting system crash.
