CVE-2023-53617

Kernel memory leak during failed SoC registration

Published Oct 7, 2025 · Updated Oct 7, 2025

Memory leak in the ASPEED SoC information driver in affected Linux kernel releases allows local users to consume kernel memory. The aspeed_socinfo_init function duplicates the root model into attrs->machine but previously omitted its release when soc_device_register returned an error. The leak occurs only if an ASPEED system reaches the driver's early initialization path and SoC-device registration fails; no data access or code execution is reported.
