CVE-2026-12502

Service-account takeover via unrestricted password reset

Published Jul 24, 2026 · Updated Jul 24, 2026

Privilege management failure in LOYTEC LINX-A64 firmware through 8.4.16 allows local users in superadmin to reset any LARM password. The set-passwd subcommand in /usr/bin/ltsudo accepts any target LARM account, including larmapp, without enforcing the intended account boundary. Membership in the superadmin group and local command access are required; successful use changes a chosen service-account password and enables control of that account.
