CVE-2026-116737
libphdi through 20260902 contains a heap out-of-bounds read vulnerability in libphdi_data_files_get_extent_data_file_path that uses the directory prefix length instead of the basename length.
Does this matter?
Lower severity and no EPSS score yet. Track it; it rarely justifies an emergency change on its own.
Description
libphdi through 20260902 contains a heap out-of-bounds read vulnerability in libphdi_data_files_get_extent_data_file_path that uses the directory prefix length instead of the basename length. Attackers can supply a crafted Parallels disk image descriptor with a long directory prefix and short basename to crash the process or expose adjacent heap memory.
