Short explanation
libfwsi through 20260522 contains a heap out-of-bounds read vulnerability in libfwsi_mtp_file_entry_values_read_data(). This allows attackers to read past buffer bounds via crafted MTP file entry shell items.
Attackers can embed specific shell items into .lnk files, jump lists, or shell bags to crash libfwsi consumers, directly threatening application availability.
What should be done?
- Monitor official vendor advisories
- Track updates since patch status is unknown
- Restrict processing of untrusted .lnk or shell files
