Medium: microcode_ctl

Issue Overview: Sensitive information accessible by physical probing of JTAG interface for some IntelR Processors with SGX may allow an unprivileged user to potentially enable information disclosure via physical access. CVE-2022-0005 A flaw was found in hw. The APIC can operate in xAPIC mode also...

The vulnerability of the kvm_irq_delivery_to_apic_fast() function in the KVM virtualization subsystem of the Linux operating system allows a attacker to trigger a service failure.

The vulnerability of the kvmirqdeliverytoapicfast function in the KVM virtualization subsystem of the Linux operating system is related to pointer arithmetic errors. Exploiting this vulnerability could allow an attacker to trigger a service failure...

CVE-2022-21233

A flaw was found in hw. The APIC can operate in xAPIC mode also known as a legacy mode, in which APIC configuration registers are exposed through a memory-mapped I/O MMIO page. This flaw allows an attacker who can execute code on a target CPU to query the APIC configuration page. When reading the...
