CVE-2026-16243: CWE-125 Out-of-bounds read in Eclipse Foundation Eclipse OMR
CVE-2026-16243 is a medium severity vulnerability in Eclipse OMR up to version 0.11 where the arraycmp SIMD implementation for Z and P architectures does not verify if the number of bytes to compare is zero, leading to an out-of-bounds read.
AI Analysis
Technical Summary
This vulnerability involves an out-of-bounds read (CWE-125) in the arraycmp SIMD implementation for Z and P architectures in Eclipse OMR versions up to 0.11. The flaw occurs because the code does not check whether the number of bytes to compare is zero before performing the operation, potentially causing memory to be read outside the intended bounds.
Potential Impact
An out-of-bounds read can lead to information disclosure or application instability. The CVSS 4.0 score of 5.7 indicates a medium impact with network attack vector, high attack complexity, partial privileges required, and user interaction needed. There is no indication of known exploits in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround has been published at this time.
