CVE-2024-38271

There exists a vulnerability in Quick Share/Nearby, where an attacker can force a victim to stay connected to a temporary hotspot created for the sharing. As part of the sequence of packets in a Quick Share connection over Bluetooth, the attacker forces the victim to connect to the attacker’s WiFi network and then sends an OfflineFrame that crashes Quick Share. This makes the Wifi connection to the attacker’s network last, instead of returning to the old network when the Quick Share session completes, allowing the attacker to be a MiTM. We recommend upgrading to version 1.0.1724.0 of Quick Share or above

Weakness

The product does not release or incorrectly releases a resource before it is made available for re-use.

Affected Software

Potential Mitigations

• Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
• For example, languages such as Java, Ruby, and Lisp perform automatic garbage collection that releases memory for objects that have been deallocated.
