CVE-2026-46115

In the Linux kernel block subsystem, CVE-2026-46115 was addressed by adding a check so that zone_device_pages_have_same_pgmap() prevents merging bvec segments that span different dev_pagemaps in biovec_phys_mergeable. Root cause: biovec_phys_mergeable() did not verify that two physically contiguo...
