UnknownEPSS 2.10%

Last modified Jun 17, 2026

CVE-2019-11772 is a vulnerability of currently unknown severity. In Eclipse OpenJ9 prior to 0.15, the String.getBytes(int, int, byte[], int) method does not verify that the provided byte array is non-null nor that the provided index is in bounds when compiled by the JIT. This allows arbitrary writes to any 32-bit address or beyond the end of a byte array within Java code run under a SecurityManager.. EPSS estimates a 2.10% chance of exploitation in the next 30 days.
