Detailsinfo

A vulnerability, which was classified as critical, has been found in zephyrproject-rtos zephyr up to 3.3 (Project Management Software). This issue affects an unknown code block of the component Bluetooth HCI Host Layer. The manipulation with an unknown input leads to a stack-based overflow vulnerability. Using CWE to declare the problem leads to CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The bluetooth HCI host layer logic not clearing a global reference to a semaphore after synchronously sending HCI commands may allow a malicious HCI Controller to cause the use of a dangling reference in the host layer, leading to a crash (DoS) or potential RCE on the Host layer.

The weakness was shared 07/10/2023 as GHSA-xvvm-8mcm-9cq3. It is possible to read the advisory at github.com. The identification of this vulnerability is CVE-2023-1901 since 04/05/2023.
