In the Linux kernel, the following vulnerability has been resolved: block: bio-integrity: Fix null-ptr-deref in bio_integrity_map_user()… (CVE-2026-64052)CVE-2026-64052 0 A null pointer dereference vulnerability in the Linux kernel's bio_integrity_map_user() function was resolved. The issue arises because pin_user_pages_fast() can partially pin pages, but bio_integrity_map_user() does not handle partial pinning properly, leading to a general protection fault when dereferencing an unpinned page address. The fix involves verifying that all requested memory is pinned and unpinning memory with an error return if partial pinning occurs.
