CVE-2026-27711

NanaZip is an open source file archive. Starting in version 5.0.1252.0 and prior to versions 6.0.1638.0 and 6.5.1638.0, a memory corruption vulnerability in NanaZip’s UFS parser allows a crafted .ufs/.ufs2/.img file to trigger out-of-bounds memory access during archive open/listing. The bug is reachable via normal user file-open flow and can cause process crash, hang, and potentially exploitable heap corruption. Versions 6.0.1638.0 and 6.5.1638.0 fix the issue.
