  <description>This update for the Linux Kernel 5.3.18-24_99 fixes several issues.

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-2022-1055: Fixed a use-after-free in tc_new_tfilter that could allow a local attacker to gain privilege escalation. (bnc#1197705)
- 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)
