The following security issues were fixed:

CVE-2022-1016: Fixed a vulnerability in the nf_tables component of the
 netfilter subsystem. This vulnerability gives an attacker a powerful
 primitive that can be used to both read from and write to relative stack
 data, which can lead to arbitrary code execution. (bsc#1197335)

CVE-2022-1011: Fixed an use-after-free vulnerability which could allow a
 local attacker to retireve (partial) /etc/shadow hashes or any other
 data from filesystem when he can mount a FUSE filesystems. (bsc#1197344)

CVE-2021-39713: Fixed a race condition in the network scheduling
 subsystem which could lead to a use-after-free (bsc#1197211).");
