CVE-2026-116731
Description
A flaw was found in Furnace. The application does not properly validate subsong indices when parsing FamiTracker module files, leading to an out-of-bounds write. By convincing a user to open a specially crafted file, an attacker can corrupt memory and cause the application to crash, resulting in a Denial of Service (DoS).
Statement
This vulnerability is rated as Moderate severity because exploitation requires local user interaction to process a maliciously crafted audio file, limiting the primary impact to application denial of service. Furthermore, the affected software is not distributed or supported within Red Hat Enterprise Linux, restricting any potential risk to community environments.
