"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmmc: core: Avoid bitfield RMW for claim/retune flags\n\nMove claimed and retune control flags out of the bitfield word to\navoid unrelated RMW side effects in asynchronous contexts.\n\nThe host->claimed bit shared a word with retune flags. Writes to claimed\nin __mmc_claim_host() or retune_now in mmc_mq_queue_rq() can overwrite\nother bits when concurrent updates happen in other contexts, triggering\nspurious WARN_ON(!host->claimed). Convert claimed, can_retune,\nretune_now and retune_paused to bool to remove shared-word coupling."
