In the Linux kernel, the following vulnerability has been resolved: mmc: core: Avoid bitfield RMW for claim/retune flags Move claimed and retune control flags out of the bitfield word to avoid unrelated RMW side effects in asynchronous contexts. The host-claimed bit shared a word with retune flag...

CVE-2026-43484

CVE-2026-43484 – Linux kernel MMC core : The vulnerability stems from concurrent updates to bitfield flags (claimed and retune_now) sharing a word, enabling write–overwrite of other bits in async contexts and triggering spurious WARN_ON(!host->claimed). The fix moves claimed, can_retune, retun...
