An update that solves four vulnerabilities and has 38 security fixes can now be installed.

Description:

The SUSE Linux Enterprise 15 SP2 Azure kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

  • CVE-2021-3659: Fixed a NULL pointer dereference in llsec_key_alloc() in net/mac802154/llsec.c (bsc#1188876).
  • CVE-2021-21781: Fixed a information disclosure vulnerability in the ARM SIGPAGE (bsc#1188445).
  • CVE-2021-22543: Fixed improper handling of VM_IO|VM_PFNMAP vmas in KVM, which could bypass RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allowed users with the ability to start and control a VM to read/write random pages of memory and can result in local privilege escalation (bsc#1186482).
