WID-SEC-2026-3419 · first 17.09.2026 · updated 29.10.2026 · CVSS 8,6
What it is about
Red Hat Enterprise Linux (RHEL) ist eine populäre Linux-Distribution. Ein Angreifer kann mehrere Schwachstellen in Red Hat Enterprise Linux ausnutzen, um beliebigen Code auszuführen, Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren oder offenzulegen oder Denial-of-Service-Zustände herbeizuführen.
Under what conditions?
The BSI does not name any particular preconditions. Exploitable remotely according to the BSI.
What can happen in the worst case
An attacker could use the vulnerability to
- beliebigen Code auszuführen
- Sicherheitsmaßnahmen zu umgehen
- Daten zu manipulieren oder offenzulegen oder Denial-of-Service-Zustände herbeizuführen
Am I affected?
Affected according to the BSI:
- IBM AIX 7.3
- IBM VIOS 4.1
- Debian Linux
- Amazon Linux 2
- IBM AIX 7.2
- Red Hat Enterprise Linux
- Fedora Linux
- IBM QRadar SIEM
- IBM MQ Operator
- RESF Rocky Linux
- SUSE Linux
