Red Hat Enterprise Linux: privilege escalation

High7.5CVE-2026-19654 · Published Aug 12, 2026 · updated Sep 24, 2026

A unauthenticated remote peer may lead rsyslogd to crash due to a flaw in the optional imptcp module. A crafted input sequence during oversize-frame recovery can cause an invalid internal message length and terminate rsyslogd. No confidentiality or integrity impact, privilege escalation, or code execution has been identified. imtcp and the default imptcp framing modes are not affected.
