CVE-2026-47224Network attack vector

Processing interruption via undersized LVM metadata CRC

Published Jun 12, 2026 · Updated Jun 12, 2026

Out-of-bounds read in NanaZip 3.0.1000.0 and later before 6.0.1698.0 allows remote attackers to interrupt processing via a crafted LVM image. CHandler::Open2 allocates the attacker-controlled metadata size, then computes CRC-32 over a fixed 508-byte span beginning at offset four without requiring a 512-byte buffer. Exploitation requires a user to open the image; with Page Heap enabled, the overread reaches a guard page and crashes the process.
