This does not restore the write permission, which\nmay cause subsequent write operations on the same file to fail.\n\nFix this by calling exe_file_allow_write_access() before filp_close() to\nrestore the write permission properly.","state":0,"publishedAt":"2025-12-16T14:21:16.889+00:00","modifiedAt":"2026-10-15T01:09:40.623+00:00","affected":[{"ecosystem":"Vendor
