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. (bnc#1197133)

Описание

A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write(). This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in privilege escalation.

Описание

A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker.
