Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-120 and the CVSS impact.

Summary

A user-provided integer option was passed to nmreq_copyin() without checking if it would overflow. This insufficient bounds checking could lead to kernel memory corruption. On systems configured to include netmap in their devfs_ruleset, a privileged process running in a jail can affect the host environment.
