# CVE-2026-15028

> 3.9 LOW · 🧪 PoC

## Beschreibung

A flaw was found in libarchive. This vulnerability allows a remote attacker to trigger a heap overflow by providing a specially crafted tar archive. The issue occurs during the parsing of a PAX extended header containing a malformed SUN.holesdata sparse-file attribute. Successful exploitation could lead to a denial of service, making the system unavailable, or potentially allow for arbitrary code execution, giving the attacker control over the affected system.
