CVE-2026-99015 at MITRE

Description

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: hci_sock: Serialize dead-device detachment

Rebinding an HCI socket after its controller is unregistered can race
monitor control replay and crash the kernel. hci_sock_bind() clears
hci_pi(sk)->hdev and drops the device reference under only the socket
lock, whereas send_monitor_control_replay() holds hci_sk_list.lock for
reading.

Replay can observe a non-NULL hdev, then bind can clear it and drop the
last reference before create_monitor_ctrl_open() reads hdev->id. This
can cause a NULL pointer dereference if the pointer is reloaded, or a
use-after-free if the old pointer is retained.

The kernel reported:

KASAN: null-ptr-deref in range [0x0000000000000068-0x000000000000006f]
RIP: 0010:create_monitor_ctrl_open+0x579/0x800
Call Trace:
hci_sock_bind+0xd96/0x1190
__sys_bind+0x166/0x200
__x64_sys_bind+0x6d/0xb0
do_syscall_64+0xdd/0x4a0
entry_SYSCALL_64_after_hwframe+0x77/0x7f

The same missing serialization lets hci_send_to_sock() select a socket
for the old device and queue its frame after bind has detached the socket
or installed a new binding.

Take hci_sk_list.lock for writing when clearing the device pointer and
resetting the socket state. This waits for existing replay and delivery
readers to finish before detachment and prevents later readers from
using the old binding. Keep hci_dev_put() outside the critical section
because the final device release can sleep.
