WID-SEC-2026-4120 · first 23.10.2026 · updated 28.10.2026 · CVSS 6,8
What it is about
Red Hat Enterprise Linux (RHEL) ist eine populäre Linux-Distribution. Ein entfernter, anonymer Angreifer kann eine Schwachstelle in Red Hat Enterprise Linux ca-certificates ausnutzen, um Sicherheitsvorkehrungen zu umgehen, vertrauliche Informationen auszulesen oder Daten zu manipulieren
Under what conditions?
Over the network and without logging in. This is the most dangerous combination: attackers can scan reachable devices automatically.
What can happen in the worst case
An attacker could use the vulnerability to
- Sicherheitsvorkehrungen zu umgehen
- vertrauliche Informationen auszulesen oder Daten zu manipulieren
Am I affected?
Affected according to the BSI:
- Red Hat Enterprise Linux
- Broadcom Fabric OS
- IBM QRadar SIEM
- RESF Rocky Linux
- SUSE Linux
- Oracle Linux
- Red Hat Enterprise Linux <ca-certificates-2026.2.92_v9.0.319-100.3.el10_2.src.rpm
- Red Hat Enterprise Linux <ca-certificates-2026.2.92_v9.0.319-100.3.el10_2.noarch.rpm
- Red Hat Enterprise Linux <ca-certificates-2026.2.92_v9.0.319-90.3.el9_8.src.rpm
- Red Hat Enterprise Linux <ca-certificates-2026.2.92_v9.0.319-90.3.el9_8.noarch.rpm
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Red Hat Enterprise Linux ca-certificates-2026.2.92_v9.0.319-100.3.el10_2.src.rpm
- Red Hat Enterprise Linux ca-certificates-2026.2.92_v9.0.319-100.3.el10_2.noarch.rpm
- Red Hat Enterprise Linux ca-certificates-2026.2.92_v9.0.319-90.3.el9_8.src.rpm
- Red Hat Enterprise Linux ca-certificates-2026.2.92_v9.0.319-90.3.el9_8.noarch.rpm
Is the vulnerability already being exploited?
None of the CVEs is in the CISA catalogue of exploited vulnerabilities. That does not mean there are no attacks, only that none are documented.
