CVE-2026-90390

A flaw was found in the Linux kernel's md/bitmap component. When the backlogstore function is called, it suspends the array before verifying the existence of a write-mostly device. If such a device is not found, the error handling path fails to resume the array, leaving it in a suspended state...
