Description
A vulnerability in the Linux kernel's ASoC sti driver was fixed by ensuring the IRQ lock is initialized before the IRQ is requested. The issue involved the uni_reader_init() function registering a shared IRQ before initializing the associated lock, which could lead to the interrupt handler being invoked while the lock was uninitialized.
