> CISA advisories cover 70+ Linux kernel flaws affecting Siemens RUGGEDCOM and SCALANCE network devices; many enable remote code execution.

Siemens has released security advisories covering multiple classes of vulnerability in the Linux kernel affecting RUGGEDCOM RST2428P and SCALANCE XC/XR series industrial Ethernet switches. The vulnerabilities span use-after-free, null pointer dereferences, buffer overflows, out-of-bounds access, race conditions, and resource exhaustion affecting kernel subsystems including netfilter, NVMe-oF/TCP, perf events, file systems (JFS, ext4, F2FS), device drivers, and networking stacks. The most critical issues enable remote code execution with CVSS scores reaching 9.1. Affected versions are all releases prior to version 3.1 of the affected product lines. Patches are available; organizations running these devices should upgrade immediately to mitigate attack surface.
