CVE-2026-31744

Summary: CVE-2026-31744 concerns the Linux kernel energy model code path that processes perf domain IDs. The function dev_energymodel_nl_get_perf_domains_doit() calls em_perf_domain_get_by_id() and uses its return value without verifying it; if a caller supplies a non-existent perf domain ID, em_...
