Red Hat Enterprise Linux (sequoia-openpgp, perl-DBI): Mehrere Schwachstellen
WID-SEC-2026-3790 · first 07.10.2026 · updated 26.10.2026 · CVSS 7,5
What it is about
Red Hat Enterprise Linux (RHEL) ist eine populäre Linux-Distribution. Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Red Hat Enterprise Linux ausnutzen, um Sicherheitsvorkehrungen zu umgehen, Daten zu manipulieren und einen Denial-of-Service-Zustand auszulösen.
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
- Daten zu manipulieren
- einen Denial-of-Service-Zustand auszulösen
Am I affected?
Affected according to the BSI:
- Red Hat Enterprise Linux
- RESF Rocky Linux
- SUSE Linux
- SUSE openSUSE
- Oracle Linux
- Red Hat Enterprise Linux 9
- Red Hat Enterprise Linux 10
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Install the updates provided by the vendor; details in the sources below.
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.
