CVE-2026-42511 (GCVE-0-2026-42511)

Vulnerability from cvelistv5 – Published: 2026-04-30 06:56 – Updated: 2026-05-01 15:25

Title

Remote code execution via malicious DHCP options

Summary

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.

Severity

8.1 (High)
