CVE-2026-97909
ASoC: sti: initialize IRQ lock before requesting IRQ
Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: sti: initialize IRQ lock before requesting IRQ uni_reader_init() registers the shared IRQ before initializing reader->irq_lock. A pending interrupt can invoke the handler while the lock is still uninitialized. Initialize the lock before registering the IRQ so the interrupt path always sees valid lock state.
