| Vector | AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N |
Name of the Vulnerable Software and Affected Versions:
BlueZ (affected versions not specified)
Linux kernel (affected versions not specified)
Description:
The issue is related to improper access control in BlueZ and a vulnerability in the Linux kernel's net/bluetooth/a2mp.c component, which lacks protection of service data. This could allow an unauthenticated user or a remote attacker to potentially enable information disclosure via adjacent access or by using specially crafted AMP packets.
Recommendations:
For BlueZ, at the moment, there is no information about a newer version that contains a fix for this vulnerability.
For Linux kernel, consider restricting access to the net/bluetooth/a2mp.c component to minimize the risk of exploitation until a patch is available.
