Description:

This update for the Linux Kernel 4.12.14-95_60 fixes several issues.

The following security issues were fixed:

• CVE-2021-22543: Fixed an issue with KVM, related to the handling of VM_IO|VM_PFNMAP vmas, which allowed users with the ability to start and control a VM to read/write random pages of memory and could result in local privilege escalation (bsc#1186482).
• CVE-2021-37576: On the powerpc platform KVM guest OS users could cause host OS memory corruption via rtas_args.nargs (bsc#1188838).
• CVE-2021-3609: Fixed a local privilege escalation via a race condition in net/can/bcm.c (bsc#1187215).
