CVE-2025-38304 Details
Description
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: Fix NULL pointer deference on eir_get_service_data The len parameter is considered optional so it can be NULL so it cannot be used for skipping to next entry of EIR_SERVICE_DATA.
A NULL pointer dereference vulnerability has been fixed in the Bluetooth component of the Linux kernel. The issue arose in the 'eir_get_service_data' function, where the 'len' parameter, considered optional, could be NULL. This NULL value could not be used to skip to the next entry of 'EIR_SERVICE_DATA', leading to a potential crash.
