    Описание

    Оригинално описание

    In the Linux kernel, the following vulnerability has been resolved: ASoC: cs35l33: drain threaded IRQ before runtime suspend cs35l33_runtime_suspend() currently switches the codec into regcache_cache_only(true) and powers it down without first quiescing the threaded IRQ registered by devm_request_threaded_irq(). That leaves a window where cs35l33_irq_thread() can still run after suspend has closed off live register access. A running system can reach this during runtime PM while the driver still has critical fault IRQs unmasked. If the threaded handler runs in that window, it reads volatile INT_STATUS_1/2 after cache_only has been enabled, ignores the regmap_read() failures, and can still drive the AMP_SHORT_RLS, CAL_ERR_RLS, OTE_RLS, and OTW_RLS release paths. Use disable_irq() before entering cache_only/power-off so any in-flight threaded handler is drained and no new IRQ thread can run during the suspended state. Re-enable the IRQ only after runtime_resume() has restored live register access with regcache_sync(). Since probe only warns if devm_request_threaded_irq() fails, track whether the IRQ was actually installed before disabling or re-enabling it.
