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...

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...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the lack of a devpagemap check in the block layer’s biovecphysmergeable function. This...
