CWE-125 Jul 21, 2026
Out-of-bounds Read in Eclipse Foundation Omr
In Eclipse OMR versions up to 0.11, the arraycmp SIMD implementation for Z and P does not check if the number of bytes to compare is zero.

CWE-120 Jan 29, 2026
Eclipse OMR port library buffer overflow in processor feature name API (CVE-2026-1188)
In the Eclipse OMR port library component since release 0.2.0, an API function to return the textual names of all supported processor features was not accounting for the separator inserted between processor features. If the output buffer supplied to this function was incorrectly sized, failing to account for the separator when determining when a write to the buffer was safe could lead to a buffer overflow. This issue is fixed in Eclipse OMR version 0.8.0.
CVE-2025-14549
High · 8.1
CWE-125 Dec 15, 2025
OMR on Z processors Exposing a possible buffer over-read problem
In the Eclipse OMR compiler component, since release 0.7.0, an optimization enabled for Eclipse OpenJ9 consumers of OMR on Z processors incorrectly handles NUL (0x00) characters during the Latin-compatible charset (UTF-8, ISO8859-1, ASCII, etc) to IBM-1047/037 translation sequence. This can cause the output byte array to be truncated, discarding the first NUL byte and all subsequent characters, and thereby exposing a possible buffer over-read problem. This issue is fixed in Eclipse OMR version 0.8.0.
