CVE-2026-46295

In the Linux kernel KVM for x86, CVE-2026-46295 stems from a race between vmx_sync_pir_to_irr() on the target vCPU and __vmx_deliver_posted_interrupt() on a sender vCPU. The sequence of operations (pi_test_and_set_pir, then pi_test_and_set_on) can interleave such that the second sync reports max_...

CVE-2026-46295 KVM: x86: Do IRR scan in __kvm_apic_update_irr even if PIR is empty

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Do IRR scan in kvmapicupdateirr even if PIR is empty Fall back to apicfindhighestvector when PID.ON is set but PIR turns out to be empty, to correctly report the highest pending interrupt from the existing IRR. In a...
