CVE-2022-50189

Local monitoring interruption via turbostat descriptor leak

Published Jun 18, 2025 · Updated May 11, 2026

Resource leakage in Linux turbostat 5.19 allows local users to interrupt monitoring through a throttle-count value that cannot be parsed. The get_core_throt_cnt function returns after fscanf fails without closing the file stream opened for the throttle-count input. Repeated failures consume turbostat file descriptors until further file operations fail; the reported consequence is limited to local monitoring availability.
