CVE-2026-112053 Schroedinger CVE debrief

Who should care

Defenders responsible for systems or applications using libschroedinger should assess exposure and prioritize verification and potential updates. This includes reviewing the current version of libschroedinger, identifying affected product deployments, and implementing input validation and sanitization measures. Additionally, defenders should monitor decoding applications for crashes or unusual behavior and review compensating controls for exposed systems.

Why it matters

CVE-2026-112053 is a MEDIUM-severity vulnerability in libschroedinger that can cause decoding applications to crash and potentially expose data. Defenders should prioritize verifying and updating libschroedinger, implementing input validation, and monitoring applications for unusual behavior.

• Potential crashes of decoding applications
• Possible data exposure through out-of-bounds reads
• Need for input validation and sanitization
• Verification of libschroedinger version and updates

Technical summary

The libschroedinger library through version 1.0.11 contains an out-of-bounds read vulnerability. This issue allows attackers to read past a static quantiser table by supplying unvalidated wavelet filter index or transform depth values. A crafted low-delay Dirac stream with a wavelet filter index of 7 or more or transform depth of 5 or 6 can cause decoding applications to crash. The vulnerability is triggered by the lack of input validation for wavelet filter index and transform depth values, allowing attackers to access sensitive data. Defenders should prioritize verifying and updating libschroedinger to prevent potential crashes and data exposure.

Defensive priority

Defenders should prioritize verifying and updating libschroedinger to prevent potential crashes and data exposure.

Recommended defensive actions

• Verify libschroedinger version and update to a fixed version if available
• Implement input validation for wavelet filter index and transform depth values
• Monitor decoding applications for crashes or unusual behavior
• Review compensating controls for exposed systems while remediation is scheduled and verified
• 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

Evidence notes

The vulnerability allows attackers to read past a static quantiser table by supplying unvalidated wavelet filter index or transform depth values. A crafted low-delay Dirac stream with a wavelet filter index of 7 or more or transform depth of 5 or 6 can crash decoding applications.
