What is CVE-2025-39981?

A vulnerability in the Linux kernel Bluetooth module can lead to a Use After Free condition. This occurs when the 'mgmt_pending' structure is freed while still being processed. Specifically, it puts the system at risk by potentially allowing access to freed memory areas, which may be exploited to cause unexpected behavior or crashes. Implementation of checks to confirm that 'mgmt_pending' is still valid ensures better protection against such conditions, addressing potential threats that could arise during the execution of Bluetooth management commands.
