Threats affecting pkg:github/libyal/libphdi

CVE-2026-116737 is a heap out-of-bounds read vulnerability in libphdi, a component of libyal. The flaw occurs in the function libphdi_data_files_get_extent_data_file_path, which incorrectly calculates buffer size by using the directory prefix length instead of the basename length. This can be triggered by a crafted Parallels disk image descriptor with a long directory prefix and a short basename, potentially causing a process crash or exposure of adjacent heap memory.
