Amazon Linux 2023 Security Advisory: ALAS2023-2026-3108
Advisory Released Date: 2026-09-29
Advisory Updated Date: 2026-09-29
Severity:
Important
Issue Overview:
A symlink-following flaw was found in libvirt's qemuTPMEmulatorPrepareHost() function. The function uses a path-based chown() on the swtpm logfile without checking for symbolic links. A local attacker with access to the swtpm account can replace the logfile with a symlink, causing libvirtd (running as root) to transfer ownership of an arbitrary file to the swtpm user. (CVE-2026-77159)
Affected Packages:
libvirt
Issue Correction:
Run dnf update libvirt --releasever 2023.12.20260928 or dnf update --advisory ALAS2023-2026-3108 --releasever 2023.12.20260928 to update your system.
More information on how to update your system can be found on this page: Amazon Linux 2023 documentation
