CVE-2025-14549OMR on Z processors Exposing a possible buffer over-read problem
Medium 6.9
In plain English
A medium-severity out-of-bounds read in Eclipse OMR from Eclipse OMR. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 23% of all known vulnerabilities).
Official description
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.
