The following security issues were fixed:

CVE-2018-25020: Fixed an issue in the BPF subsystem in the Linux kernel
 mishandled situations with a long jump over an instruction sequence
 where inner instructions require substantial expansions into multiple
 BPF instructions, leading to an overflow. (bsc#1193575)

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-2020-25670, CVE-2020-25671, CVE-2020-25672, CVE-2020-25673,
 CVE-2021-23134: Fixed multiple bugs in NFC subsystem (bsc#1178181,
 bsc#1186060).

CVE-2019-0136: Fixed an insufficient access control which allow an
 unauthenticated user to execute a denial of service. (bsc#1193157)

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).");
