In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: msft: fix slab-use-after-free in msft_do_close() Tying the
msft->data lifetime to hdev by freeing it in hci_release_dev() to fix the
following case: [use] msft_do_close() msft = hdev->msft_data; if (!msft)
…(1) <- passed. return; mutex_lock(&msft->filter_lock); …(4) <- used
after freed. [free] msft_unregister() msft = hdev->msft_data;
hdev->msft_data = NULL; …(2) kfree(msft); …(3) <- msft is freed.
