CVE-2026-55781 NanaZip: Unbounded memory allocation (DoS) in NanaZip UFS parser via unvalidated fs_bsize/fs_fsize superblock fields

NanaZip is the 7-Zip derivative intended for the modern Windows experience. Prior to 6.5.1749.0, NanaZip's UFS and FFS image handler in NanaZip.Codecs.Archive.Ufs.cpp validates the superblock block size only against the MINBSIZE lower bound and does not validate the fsfsize fragment size, allowin...

CVE-2026-55781

The CVE affects NanaZip (7-Zip derivative) prior to version 6.5.1749.0, specifically the UFS/FFS image handler in NanaZip.Codecs.Archive.Ufs.cpp. The root cause is that superblock considerations validate the block size only against MINBSIZE and do not validate the fs_fsize fragment size, allowing...
