In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
ASoC: cs35l33: drain threaded IRQ before runtime suspend<\/p>\n
cs35l33_runtime_suspend() currently switches the codec into
\nregcache_cache_only(true) and powers it down without first quiescing the
\nthreaded IRQ registered by devm_request_threaded_irq(). That leaves a
\nwindow where cs35l33_irq_thread() can still run after suspend has closed
\noff live register access.<\/p>\n
A running system can reach this during runtime PM while the driver still
\nhas critical fault IRQs unmasked. If the threaded handler runs in that
\nwindow, it reads volatile INT_STATUS_1\/2 after cache_only has been
\nenabled, ignores the regmap_read() failures, and can still drive the
\nAMP_SHORT_RLS, CAL_ERR_RLS, OTE_RLS, and OTW_RLS release paths.<\/p>\n
Use disable_irq() before entering cache_only\/power-off so any in-flight
\nthreaded handler is drained and no new IRQ thread can run during the
\nsuspended state. Re-enable the IRQ only after runtime_resume() has
\nrestored live register access with regcache_sync(). Since probe only
\nwarns if devm_request_threaded_irq() fails, track whether the IRQ was
\nactually installed before disabling or re-enabling it.<\/p>\n","protected":false},"excerpt":{"rendered":"
