Detailsinfo

A vulnerability classified as critical has been found in Linux Kernel up to 6.1.141/6.6.93/6.12.33/6.15.2/6.16-rc1. This affects the function eir_get_service_data of the component Bluetooth. The manipulation of the argument len with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. The summary by CVE is:

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.
