CVE-2026-43309

The CVE-2026-43309 issue affects the Linux kernel’s md raid and device-mapper (dm-raid) components. When stopping a RAID array managed by dm-raid, the system could hang because md_stop() attempted to flush the write-intent bitmap to metadata sub-devices that were already suspended. The fix preven...
