CVE-2026-89770

CVE-2026-89770 is a NULL pointer dereference in the Linux kernel's iomap subsystem . When PI (Protection Information) verification is disabled on a block device, fs_bio_integrity_alloc may fail to allocate a bio integrity payload. The function iomap_bio_read_folio_range_sync then calls fs_bio_int...
