CVE-2026-19654: Red Hat Enterprise Linux

High severity, CVSS 7.5. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Red Hat Enterprise Linux: version 6.0 only; version 7.0 only; version 8.0 only; version 9.0 only; version 10.0 only
• Rsyslog Rsyslog: from 8.36.0, before 8.2608.0 (fixed in 8.2608.0)
