CVE-2026-122329
Description
A flaw was found in SDL_mixer. The library's Audio Interchange File Format (AIFF) decoder miscalculates memory offsets when decompressing audio samples, resulting in a stack-based buffer overflow. An attacker could exploit this vulnerability by supplying a specially crafted audio file, potentially allowing arbitrary code execution or causing the application to crash, leading to a Denial of Service (DoS).
Statement
This vulnerability is rated as having an Important severity because successful exploitation can lead to arbitrary code execution or application termination in the context of the user opening the file. Triggering this flaw requires user interaction, specifically convincing a user or service to parse an untrusted AIFF audio track in an application utilizing the SDL mixer library. In typical Red Hat Enterprise Linux deployments, this library is primarily utilized by multimedia or gaming applications rather than core system daemons, constraining the blast radius to the permissions of the calling user process.
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.
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.
