The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-099445 advisory.

    GNU patch is vulnerable to a NULL pointer dereference when processing a specially crafted unified-diff     patch file. Improper handling of consecutive end-of-file newline markers can corrupt internal hunk (single     block of changes in diff) data structures, causing the application to pass a NULL pointer to fwrite()     during patch processing.
    An attacker can trigger this condition with a malicious patch file, causing the utility to crash and     resulting in a denial of service.



    This issue has been fixed in the commit e6d6a4e021660679d7fc9150f981d4920f722313
