CVE-2026-43484

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mmc: core: Avoid bitfield RMW for claim/retune flags<br /> <br /> Move claimed and retune control flags out of the bitfield word to<br /> avoid unrelated RMW side effects in asynchronous contexts.<br /> <br /> The host-&gt;claimed bit shared a word with retune flags. Writes to claimed<br /> in __mmc_claim_host() or retune_now in mmc_mq_queue_rq() can overwrite<br /> other bits when concurrent updates happen in other contexts, triggering<br /> spurious WARN_ON(!host-&gt;claimed). Convert claimed, can_retune,<br /> retune_now and retune_paused to bool to remove shared-word coupling.
