The vulnerability in the net/bluetooth/mgmt.c module of the Linux operating system allows a hacker to cause a service failure.

The vulnerability in the net/bluetooth/mgmt.c module of the Linux operating system is related to insufficient input data validation. Exploiting this vulnerability can allow an attacker to cause a service failure...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: MGMT: Fixed possible UAFs This attempt to fix possible UAFs is due to the fact that the struct mgmtpending is freed while it is still being processed, as seen in the following trace. To address this issue,...

CVE-2026-43059

A flaw was found in the Linux kernel's Bluetooth Management MGMT component. This vulnerability arises from incorrect handling of pending commands within the Bluetooth subsystem's command completion processes. An attacker with local access could exploit this issue to trigger memory corruption and...
