WID-SEC-2026-1453 · first 11.05.2026 · updated 15.10.2026 · CVSS 6,5
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 beliebigen Programmcode auszuführen oder um einen Denial-of-Service-Zustand zu verursachen.
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
- beliebigen Programmcode auszuführen oder um einen Denial-of-Service-Zustand zu verursachen

- RESF Rocky Linux 9
- RESF Rocky Linux 10
- Red Hat Enterprise Linux Update Infrastructure 5.1
- IBM QRadar SIEM <7.5.0 UP15 IF04
- IBM Security Verify Access
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
