Kernel memory exhaustion via input-device leak
Published Jan 19, 2025 · Updated May 11, 2026
Resource leak in the Linux AT91 ADC driver allows local administrative users to consume kernel memory through repeated failed driver binding. The at91_ts_register() error path frees st->ts_input before the newly allocated input device is stored there, leaving that allocation unreleased. Triggering the condition requires root or CAP_SYS_ADMIN access to rebind the driver and a specific AT91 touchscreen hardware configuration.
