CVE-2026-42511

Medienbericht

Remote code execution via malicious DHCP options

The BOOTP file field is written to the lease file without escaping embedded double-quotes, allowing injection of arbitrary dhclient.conf directives.  When the lease file is subsequently re-parsed by dhclient, e.g., after a system restart, an attacker-controlled field from the lease is passed to dhclient-script(8), which evaluates it.

A rogue DHCP server may be able to execute arbirary code as root on a system running dhclient.
