kernel: Bluetooth: MGMT: Fix possible UAFs

A flaw was found in the Linux kernel’s Bluetooth management subsystem net/bluetooth/mgmt.c. The mgmtpending structure may be freed while still being processed, or remain on the pending command list, which allows a use-after-free or double-free scenario. An attacker with local access to the system...
