SUSE CVE-2026-6103

phartarnumber parses the octal size field of a TAR header into a uint32t with no overflow check. The field is 11 octal digits wide and holds values up to 0x1FFFFFFFF, so a size above 0xFFFFFFFF silently wraps. The parser then skips the wrong number of data blocks and interprets attacker-controlle...
