   - CVE-2020-3702: Fixed a bug which could be triggered with specifically
     timed and handcrafted traffic and cause internal errors in a WLAN device
     that lead to improper layer 2 Wi-Fi encryption with a consequent
     possibility of information disclosure. (bsc#1191193)
   - CVE-2021-42739: The firewire subsystem had a buffer overflow related to
     drivers/media/firewire/firedtv-avc.c and
     drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandled
     bounds checking (bsc#1184673).
