CVE-2022-50547

Local denial of service via registration memory leak

Published Oct 7, 2025 · Updated Oct 7, 2025

Memory leakage in the solo6x10 media driver in affected Linux kernel releases allows local users to exhaust kernel memory. The solo_sysfs_init error path retains the device reference when device_register fails, so the name allocated by dev_set_name is never released through kobject cleanup. The condition requires initialization of a supported Solo6x10 PCI capture card and a device-registration failure; no remote path is reported.
