CVE-2026-64052

A flaw was found in the Linux kernel's bio-integrity module. The biointegritymapuser function does not correctly handle partially pinned user pages, which can occur when pinuserpagesfast returns fewer pages than requested. This oversight leads to a null-pointer dereference when attempting to acce...

CVE-2026-53365
