CVE-2022-30785Public exploit

Root code execution via exposed heap address

Published May 26, 2022 · Updated Aug 3, 2024

Privilege escalation in Tuxera NTFS-3G 2021.8.22 and earlier allows local users to execute arbitrary code as root. In libfuse-lite/fuse.c, fuse_lib_opendir returns the heap address of struct fuse_dh as a directory handle, and fuse_lib_readdir dereferences that value without validation. Exploitation requires local access and an SUID-root ntfs-3g binary; successful exploitation grants UID 0 code execution.
