"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: ufs: core: mcq: Fix &hwq->cq_lock deadlock issue\n\nWhen ufshcd_err_handler() is executed, CQ event interrupt can enter waiting\nfor the same lock. This can happen in ufshcd_handle_mcq_cq_events() and\nalso in ufs_mtk_mcq_intr(). The following warning message will be generated\nwhen &hwq->cq_lock is used in IRQ context with IRQ enabled.
