PUBLISHED
CVSS 7.5 HIGH
Reported by redhat · Published August 12, 2026
A unauthenticated remote peer may lead rsyslogd to crash due to a flaw in the optional imptcp module.

No confidentiality or integrity impact, privilege escalation, or code execution has been identified. imtcp and the default imptcp framing modes are not affected.
