CVE-2026-89727 KVM: arm64: GICv2: Don't WARN on out-of-range GICV_DIR INTID

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: GICv2: Don't WARN on out-of-range GICVDIR INTID vgicv2deactivate passes the INTID a guest wrote to GICVDIR straight to vgicgetvcpuirq, and treats a failed lookup as a "can't happen" condition with WARNONONCE. The gues...

CVE-2026-89727

CVE-2026-89727 affects the Linux kernel KVM arm64 GICv2 implementation. In vgic_v2_deactivate(), a guest-written INTID is passed directly to vgic_get_vcpu_irq(), where a failed lookup triggers WARN_ON_ONCE()—treated as a "can't happen" condition. Since GICv2 has no LPIs, any INTID outside the SGI...

CVE-2026-80939 wifi: rtw89: pci: add .shutdown callback to stop rfkill polling on reboot

In the Linux kernel, the following vulnerability has been resolved: wifi: rtw89: pci: add .shutdown callback to stop rfkill polling on reboot Since the hardware rfkill polling was introduced, arm64 platforms can panic with an asynchronous SError during warm reboot: SError Interrupt on CPU8, code...

CVE-2026-80939

CVE-2026-80939 affects the Linux kernel rtw89 PCI WiFi driver on arm64 platforms. The root cause is a missing .shutdown callback: during warm reboot the kernel invokes device_shutdown() but not .remove(), so the rfkill polling workqueue continues issuing MMIO reads to the PCI device after the PCI...
