In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_sync: hold conn in hci_past_sync() callback Avoids giving freed pointers to hci_conn_valid(), which kmalloc may have reused. Hold refcount to avoid that.Referenceshttps://git.kernel.org/stable/c/e6792adef614b389141b142e30ee549e4a47dd7dhttps://git.kernel.org/stable/c/abf9753edf3f88282c44a605f3945d8d4f8dd86c
