Summary
CVE-2023-1902 is a vulnerability affecting the Bluetooth HCI (Host Controller Interface) host layer logic. Malicious HCI Controllers can exploit this issue by failing to clear a global reference to a state pointer after handling connection events. This results in a dangling reference within the host layer, potentially leading to a denial-of-service (DoS) crash or even remote code execution (RCE) on the host layer.
