CVE-2026-112200: Resource exhaustion from unreleased AR and RPC session on RPC requests with incorrect endianness
- Severity: high (CVSS 8.7 v4.0)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.4% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2026-10-29 · updated 2026-10-29
- Weakness: CWE-772
Description
P-Net before 1.0.3 does not release the Application Relationship (AR) and the RPC session when an RPC request is rejected because its data representation has incorrect endianness. The session and its AR remain allocated, so repeated requests exhaust the available sessions. Once they are exhausted the device no longer answers new RPC requests, including Connect, until it is restarted. A remote unauthenticated attacker can use this to cause a denial of service.
Affected products
