No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

SMP security request (from peripheral) does not include the maximum encryption key size supported. Using a key with less than the maximum keysize makes brute-forcing the key easier. See V6 in BLERP paper linked below.
