CVE-2023-42189Public exploitNetwork attack vector

Unauthenticated device denial of service via IPK deletion

Published Oct 10, 2023 · Updated Nov 26, 2024

Incorrect permissions in Matter SDK 1.1.0.0 allow remote attackers to interrupt affected smart-device communications via KeySetRemove. KeySetRemove accepts an empty request or GroupKeySetID 0, returns success instead of INVALID_COMMAND, and deletes the Identity Protection Key. Unauthenticated network access is sufficient; later CASE exchanges fail with invalid-parameter or no-shared-root errors, leaving the device unable to communicate.
