CVE-2026-89727

A flaw was found in the Kernel-based Virtual Machine KVM for ARM64 arm64 architecture. A malicious guest operating system can provide an interrupt ID INTID that is outside the expected range to the GICv2 Generic Interrupt Controller version 2 during interrupt deactivation. This can trigger a...

CVE-2026-89727

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-2024-46707 KVM: arm64: Make ICC_*SGI*_EL1 undef in the absence of a vGICv3

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Make ICCSGIEL1 undef in the absence of a vGICv3 On a system with a GICv3, if a guest hasn't been configured with GICv3 and that the host is not capable of GICv2 emulation, a write to any of the ICCSGIEL1 registers is...

arm: vgic: Out-of-bound access when sending SGIs

ISSUE DESCRIPTION ARM guests can send SGI i.e. IPI targeting a list of vCPUs using the MMIO register GICDSGIR GICv2 or System Register ICCSGI1R GICv3. However, the emulation code does not sanitize the list and will directly access an array without checking whether the array index is within bounds...

CVE-2015-0268

CVE-2015-0268 affects Xen 4.5.x on ARM with GIC version 2. The vulnerable function is vgic_v2_to_sgi in arch/arm/vgic-v2.c; a guest writing an invalid value to the GICD.SGIR register can trigger a host denial of service (host crash). Several connected sources corroborate the impact as a local-gue...

CVE-2015-0268

The vgicv2tosgi function in arch/arm/vgic-v2.c in Xen 4.5.x, when running on ARM hardware with general interrupt controller GIC version 2, allows local guest users to cause a denial of service host crash by writing an invalid value to the GICD.SGIR register...
