Threats affecting pkg:github/eclipse-omr/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.

CVE-2026-1188 is a medium severity buffer overflow vulnerability in the Eclipse OMR port library component versions starting from 0.2.0. The flaw arises because an API function that returns textual names of supported processor features miscalculates the required buffer size by not accounting for separators between features. This can lead to a buffer overflow if the output buffer is undersized, potentially causing memory corruption. The vulnerability requires no authentication or user interaction and can be exploited remotely. It is fixed in Eclipse OMR version 0.8.0. Although no known exploits are currently reported in the wild, the vulnerability poses a risk to systems using affected versions of Eclipse OMR, particularly in environments where this library is integrated.
