How to fix?

Upgrade Debian:10 bluez to version 5.50-1.2~deb10u2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream bluez package and not the bluez package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

In BlueZ before 5.55, a double free was found in the gatttool disconnect_cb() routine from shared/att.c. A remote attacker could potentially cause a denial of service or code execution, during service discovery, due to a redundant disconnect MGMT event.
