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-2021-47362

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...
