In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: fix missing sevdecommission in sevreceivestart DECOMMISSION the current SEV context if binding an ASID fails after RECEIVESTART. Per AMD's SEV API, RECEIVESTART generates a new guest context and thus needs to be paired...

CVE-2021-47390

CVE-2021-47390 concerns the Linux kernel KVM path on x86, where KASAN reports a stack-out-of-bounds access in kvm_make_vcpus_request_mask() when handling IOAPIC indirect requests. The root cause is that the vcpu_bitmap is allocated as a single stack long instead of a size equal to KVM_MAX_VCPUS, ...

CVE-2021-47389

CVE-2021-47389 is a Linux kernel/KVM SVM issue related to SevReceiveStart and SEV context decommission. The root cause was a missing SEV decommission step when ASID binding fails after RECEIVE_START, which can leak firmware memory and eventually prevent allocating new SEV guest contexts, causing ...

CVE-2021-47362

CVE-2021-47362 affects the Linux kernel’s drm/amd/pm power management code. The vulnerability occurs during DPM initialization when set_power_state reads values from the current state; if current state is not populated, this can lead to a NULL pointer dereference. The ATCS/ACPI path for PCI speed...

CVE-2021-47348

The CVE-2021-47348 issue affects the Linux kernel, specifically the DRM AMD display path. The root cause is HDCP over-read/corruption due to reading 8 bytes instead of the targeted 5 bytes for a field; this could yield a corrupted value if trailing bytes are non-zero. The fix introduces a properl...
