CVE-2026-50265

Root code execution via newline property injection

Published Jun 5, 2026 · Updated Jun 5, 2026

CRLF injection in libinput-device-group allows local users to execute code as root through crafted uinput or uhid device metadata. The helper prints an unescaped phys sysattr as KEY=VALUE data, so an embedded newline creates a second udev property such as REMOVE_CMD. The supplied identifier is rejected as a duplicate of CVE-2026-50292; exploitation requires access to /dev/uinput or /dev/uhid, which is normally root-restricted.
