In the Linux kernel, the following vulnerability has been resolved: scsi: ufs: core: mcq: Fix &hwq->cq_lock deadlock issue When ufshcd_err_handler() is executed, CQ event interrupt can enter waiting for the same lock. This can happen in ufshcd_handle_mcq_cq_events() and also in ufs_mtk_mcq_intr(). The following warning message will be generated when &hwq->cq_lock is used in IRQ context with IRQ enabled. Use ufshcd_mcq_poll_cqe_lock() with spin_lock_irqsave instead of spin_lock to resolve the deadlock issue. [name:lockdep&]WARNING: inconsistent lock state [name:lockdep&]------------------------
