CVE-2026-111157
Description
A flaw was found in SoX. An attacker can exploit this vulnerability by tricking a user or automated system into opening a specially crafted WAV audio file. During audio decoding, an invalid block sample value causes a heap-based out-of-bounds write, leading to an application crash, resulting in a Denial of Service (DoS), or potential memory corruption.
Statement
Red Hat has evaluated this vulnerability as having a Moderate impact because successful exploitation requires user interaction to process an untrusted audio file, restricting the blast radius to the executing process. In Red Hat Enterprise Linux, SoX operates as a command-line utility or shared library rather than a persistently listening network service. Consequently, the primary outcome of exploitation is an application crash or process termination, limiting systemic risk without additional vulnerability chaining.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Integrity
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Write operations could cause memory corruption. In some cases, an adversary can modify control data such as return addresses in order to execute unexpected code.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
Attempting to access out-of-range, invalid, or unauthorized memory could cause the product to crash.
Other
Technical Impact: Unexpected State
Subsequent write operations can produce undefined or unexpected results.
