CVE-2026-112012 True Audio CVE debrief

Who should care

Defenders responsible for applications using libtta should assess exposure and prioritize verification of the libtta version used. They should also review decoding applications for potential stack memory corruption and monitor for potential exploitation attempts. Defenders should care about CVE-2026-112012 because it is a stack out-of-bounds read and write vulnerability in libtta through version 2.3, which can lead to potential stack memory corruption, and

Why it matters

Defenders should care about CVE-2026-112012 because it is a stack out-of-bounds read and write vulnerability in libtta through version 2.3, which can lead to potential stack memory corruption, denial of service, and arbitrary code execution. Defenders responsible for applications using libtta should assess exposure and prioritize verification of the libtta version used.

• Potential stack memory corruption in decoding applications
• Possible denial of service due to application crashes
• Potential for attackers to execute arbitrary code

Technical summary

The vulnerability exists in the tta_decoder_process_stream() and tta_decoder_process_frame() functions due to a lack of header checks, allowing a zero channel count. This can lead to decorrelation accesses cache[-1] with stream-derived values, corrupting stack memory in decoding applications. The vulnerability affects libtta through version 2.3 and can lead to potential stack memory corruption, denial of service, and arbitrary code execution. Defenders should prioritize verifying the version of libtta used in their applications and consider updating to a version that fixes this vulnerability.

Defensive priority

Defenders should prioritize verifying the version of libtta used in their applications and consider updating to a version that fixes this vulnerability.

Recommended defensive actions

• Verify the version of libtta used in applications and consider updating to a fixed version
• Review decoding applications for potential stack memory corruption
• Monitor for potential exploitation attempts
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed

Evidence notes

The vulnerability was discovered in libtta through version 2.3. The CVE record and NVD entry provide details on the vulnerability. Further information is limited, but defenders should verify the libtta version used in their applications and review decoding applications for potential stack memory corruption. The vulnerability allows a zero channel count, leading to decorrelation accesses cache[-1] with stream-derived values, corrupting stack memory in decoding applications. Evidence is limited to public CVE and NVD records.
