CVE-2025-37885

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Reset IRTE to host control if new route isn't postable Restore an IRTE back to host control remapped or posted MSI mode if the new GSI route prevents posting the IRQ directly to a vCPU, regardless of the GSI routing typ...

CVE-2025-37885 KVM: x86: Reset IRTE to host control if *new* route isn't postable

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Reset IRTE to host control if new route isn't postable Restore an IRTE back to host control remapped or posted MSI mode if the new GSI route prevents posting the IRQ directly to a vCPU, regardless of the GSI routing typ...

kernel: KVM: NULL pointer dereference in kvm_irq_delivery_to_apic_fast()

A flaw was found in the Linux kernel’s KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a...
