CISA's summary
Summary: Several SIMATIC CP devices contain direct memory access vulnerabilities that could allow an attacker to execute code, access the PROFINET network without restrictions or perform denial of service attacks. Siemens recommends specific countermeasures for products where updates are not, or not yet available.

Vulnerabilities in this advisory
- CVE-2023-37194 — CVE-2023-37194 · CWE-284
The kernel memory of affected devices is exposed to user-mode via direct memory access (DMA) which could allow a local attacker with administrative privileges to execute arbitrary code on the host system without any restrictions.
- CVE-2023-37195 — CVE-2023-37195 · CWE-400
Affected devices insufficiently control continuous mapping of direct memory access (DMA) requests. This could allow local attackers with administrative privileges to cause a denial of service situation on the host. A physical power cycle is required to get the system working again.
