CVE-2026-80673

Linux kernel NTFS driver contains a slab out-of-bounds read in ntfs_external_attr_find(). When resolving an attribute lookup with a non-zero @lowest_vcn, the function reads lowest_vcn (offset 8) and name_offset from the next $ATTRIBUTE_LIST entry without full bounds validation, allowing a crafted...

CVE-2026-80672

CVE-2026-80672 is a u16 truncation in the Linux kernel's in-kernel NTFS driver, specifically in ntfs_check_restart_area(). The variable ra_len is declared as u16, but the computed length of the $LogFile log client record array can exceed 65535 (e.g., log_clients of 410 yields 65600), causing trun...
