CVE-2024-3933: Eclipse Open J9 With -Xgc:concurrentScavenge on IBM Z, could write/read outside of a buffer

Noroxi assessment

Priority: Monitor (action score 29/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.20% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Eclipse Foundation Open J9 0.44.0.
  • Severity is disputed: the assigning authority (CNA) scores it 5.3, NVD 7.3.

Low priority for now. Upgrade to Eclipse Foundation Open J9 0.44.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In Eclipse OpenJ9 release versions prior to 0.44.0 and after 0.13.0, when running with JVM option -Xgc:concurrentScavenge, the sequence generated for System.arrayCopy on the IBM Z platform with hardware and software support for guarded storage [1], could allow access to a buffer with an incorrect length value when executing an arraycopy sequence while the Concurrent Scavenge Garbage Collection cycle is active and the source and destination memory regions for arraycopy overlap. This allows read and write to addresses beyond the end of the array range.
