Description Wolfgang Frisch 2020-07-02 07:26:18 UTC 
CVE-2020-15469

A NULL pointer dereference issue was found in various system emulators of QEMU. It could occur while performing MMIO r/w operations, in case the respective handler function is not defined. A privileged guest user able to invoke MMIO operation may use this flaw to crash the QEMU process on the host resulting in DoS scenario.

Comment 1 Wolfgang Frisch 2020-07-02 09:03:32 UTC 
My assessment of the bug, following a brief investigation of the upstream patches, is as such:

SUSE:SLE-11:Update       kvm       Not affected [1]
SUSE:SLE-11:Update       qemu      Not affected [1]
SUSE:SLE-11-SP1:Update   kvm       Not affected [1]
SUSE:SLE-11-SP3:Update   kvm       Affected [2]
SUSE:SLE-11-SP4:Update   kvm       Affected [2]
SUSE:SLE-12-SP2:Update   qemu      Affected
SUSE:SLE-12-SP3:Update   qemu      Affected
SUSE:SLE-12-SP4:Update   qemu      Affected
SUSE:SLE-12-SP5:Update   qemu      Affected
SUSE:SLE-15:Update       qemu      Affected
SUSE:SLE-15-SP1:Update   qemu      Affected
SUSE:SLE-15-SP2:Update   qemu      Affected

[1] No affected devices present.
[2] None of the affected devices exists except one (sPAPR PCI host), which does have the operation .read = NULL defined. I'm not sure if the NULL pointer dereference can be reached. It probably won't hurt to to replace it with a stub.

Please verify.
