Security update for the Linux Kernel (Live Patch 20 for SLE 12 SP4) SUSE Patch security@suse.de SUSE Security Team SUSE-SU-2022:1320-1 Final 1 1 2022-04-23T19:04:03Z current 2022-04-23T19:04:03Z 2022-04-23T19:04:03Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for the Linux Kernel (Live Patch 20 for SLE 12 SP4) This update for the Linux Kernel 4.12.14-95_74 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-2022-1011: 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). - CVE-2022-27666: Fixed a buffer overflow vulnerability in IPsec ESP transformation code. This flaw allowed a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation.
