CVE-2026-43484

A flaw was found in the Linux kernel's MultiMediaCard MMC core. Concurrent updates to bitfield flags, specifically 'claimed' and 'retunenow', can lead to unintended overwrites of other bits in asynchronous contexts. This can trigger spurious warnings and result in system instability or unexpected...
