CVE-2026-80859

A flaw was found in the Linux kernel's FUSE Filesystem in Userspace subsystem. A missing memory barrier when checking the readiness of io-uring queues could allow a CPU to observe an inconsistent state. This inconsistency can bypass a critical check, potentially reintroducing a lock-order inversi...
