CVE-2025-68383 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. Improper Validation of Specified Index, Position, or Offset in Input (CWE-1285) in Filebeat Syslog parser and the Libbeat Dissect processor can allow a user to trigger a Buffer Overflow (CAPEC-100) and cause a denial of service (panic/crash) of the Filebeat process via either a malformed Syslog message or a malicious tokenizer pattern in the Dissect configuration.. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
