exploit/multi/browser/java_atomicreferencearray checkedAt: '2026-09-21T15:23:32.367Z' --- ## Overview Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 2 and earlier, 6 Update 30 and earlier, and 5.0 Update 33 and earlier allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Concurrency. NOTE: the previous information was obtained from the February 2012 Oracle CPU. Oracle has not commented on claims from a downstream vendor and third party researchers that this issue occurs because the AtomicReferenceArray class implementation does not ensure that the array is of the Object[] type, which allows attackers to cause a denial of service (JVM crash) or bypass Java sandbox restrictions. NOTE: this issue was originally mapped to CVE-2011-3571, but that identifier was already assigned to a different issue. ## Affected - `jre = 1.5.0` - `jre = 1.6.0` - `jre = 1.7.0` - `debian_linux = 6.0` - `debian_linux = 7.0` - `linux_enterprise_desktop = 10` - `linux_enterprise_java = 10` - `linux_enterprise_java = 11` - `linux_enterprise_server = 10` - `linux_enterprise_server = 11` - `linux_enterprise_software_development_kit = 11` ## Remediation Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
