  The following security bugs were fixed:

  - CVE-2020-11669: An issue was discovered on the powerpc platform.
  arch/powerpc/kernel/idle_book3s.S did not have save/restore
  functionality for PNV_POWERSAVE_AMR, PNV_POWERSAVE_UAMOR, and
  PNV_POWERSAVE_AMOR, aka CID-53a712bae5dd (bnc#1169390).

  - CVE-2020-8834: KVM on Power8 processors had a conflicting use of
  HSTATE_HOST_R1 to store r1 state in kvmppc_hv_entry plus in
  kvmppc_{save, restore}_tm, leading to a stack corruption. Because of
  this, an attacker with the ability run code in kernel space of a guest
  VM can cause the host kernel to panic. There were two commits that,
  according to the reporter, introduced the vulnerability: f024ee098476
  ('KVM: PPC: Book3S HV: Pull out TM state save/restore into separate
  procedures') 87a11bb6a7f7 ('KVM: PPC: Book3S HV: Work around XER[SO] bug
  in fake suspend mode') (bnc#1168276).

  - CVE-2020-11494: An issue was discovered in slc_bump in
  drivers/net/can/slcan.c, which allowed attackers to read uninitialized
  can_frame data, potentially containing sensitive information from kernel
  stack memory, if the configuration lacks CONFIG_INIT_STACK_ALL, aka
  CID-b9258a2cece4 (bnc#1168424).

  - CVE-2019-9458: In the video driver there is a use after free due to a
  race condition. This could lead to local escalation of privilege with no
  additional execution privileges needed. User interaction is not needed
  for exploitation (bnc#1168295).

  - CVE-2019-3701: An issue was discovered in can_can_gw_rcv in
  net/can/gw.c. The CAN frame modification rules allow bitwise logical
  operations that can be also applied to the can_dlc field. The privileged
  user 'root' with CAP_NET_ADMIN can create a CAN frame modification rule
  that made the data length code a higher value than the available CAN
  frame data size. In combination with a configured checksum calculation
  where the result is stored relatively to the end of the data (e.g.
  cgw_csum_xor_rel) the tail of the skb (e.g. frag_list pointer in
  skb_shared_info) can be rewritten which finally can cause a system
  crash. Because of a missing check, the CAN drivers may write arbitrary
  content beyond the data registers in the CAN controller's I/O memory
  when processing can-gw manipulated outgoing frames (bnc#1120386).

  - CVE-2020-10942: In get_raw_socket in drivers/vhost/net.c lacked
  validation of an sk_family field, which might allow attackers to trigger
  kernel stack corruption via crafted system calls (bnc#1167629).
