CVE-2026-89578

CVE-2026-89578 affects the Linux kernel's dm-io component. In do_region(), DM_IO_BIO requests rebuilt each destination bio by walking the source bio's biovec and re-adding pages individually, using sector-based accounting . When a misaligned O_DIRECT buffer was split across pages, the vector leng...
