Amazon Linux 2023 Security Advisory: ALAS2023-2026-2118
Advisory Released Date: 2026-08-31
Advisory Updated Date: 2026-08-31
Severity:
Important
Issue Overview:
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. (CVE-2026-19654)
Affected Packages:
rsyslog
Issue Correction:
Run dnf update rsyslog --releasever 2023.12.20260831 or dnf update --advisory ALAS2023-2026-2118 --releasever 2023.12.20260831 to update your system.
