CVE-2026-110660
Description
A flaw was found in vgmstream. An attacker can cause a Denial of Service (DoS) by tricking a user or application into processing a specially crafted audio file. Due to missing boundary checks within the G.722.1 audio decoder, reading malformed input causes an out-of-bounds read on the stack during format detection, crashing the application.
Statement
This vulnerability is rated as having a Low impact by Red Hat because exploitation is limited to a local denial of service that requires user interaction to open an untrusted media file, without threatening system confidentiality or integrity. In standard Red Hat enterprise environments, vgmstream is not included or configured as a default system service, drastically limiting potential exposure. Successful exploitation terminates only the client application attempting to parse the malformed audio stream, restricting the blast radius strictly to the active user session.
Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Memory
An attacker could get secret values such as cryptographic keys, PII, memory addresses, or other information that could be used in additional attacks.
Confidentiality
Technical Impact: Bypass Protection Mechanism
Out-of-bounds memory could contain memory addresses or other information that can be used to bypass ASLR and other protection mechanisms in order to improve the reliability of exploiting a separate weakness for code execution.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
An attacker could cause a segmentation fault or crash by causing memory to be read outside of the bounds of the buffer. This is especially likely when the code reads a variable amount of data and assumes that a sentinel exists to stop the read operation, such as a NUL in a string.
Other
Technical Impact: Varies by Context
The read operation could produce other undefined or unexpected results.
