CVE-2025-13425: OSV-SCALIBR has NULL Pointer Dereference

A bug in the filesystem traversal fallback path causes fs/diriterate/diriterate.go:Next() to overindex an empty slice when ReadDir returns nil for an empty directory, resulting in a panic (index out of range) and an application crash (denial of service) in OSV-SCALIBR.

Root Cause Analysis

The vulnerability is a denial-of-service caused by a panic due to an index-out-of-range error in the Next() function within fs/diriterate/diriterate.go. The analysis of the provided patch commit e67c4e198ca099cb7c16957a80f6c5331d90a672 clearly shows the modification in the Next function. The original code's check i.files != nil was insufficient because an empty slice is not nil, which could lead to incorrect logic flow when dealing with empty directories in the filesystem traversal fallback path. The fix replaces this with len(i.files) > 0, which correctly handles empty directories and prevents the panic. Therefore, the diriterate.DirIterator.Next function is identified as the vulnerable function.
