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 warning condition in the host kernel, potentially leading to a host system crash and resulting in a Denial of Service (DoS) for the host.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Red Hat Enterprise Linux 10 · no fix planned: Red Hat Enterprise Linux 10 · updated 2026-09-15 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-89727.json)\n\n**kernel: KVM: arm64: GICv2: Don't WARN on out-of-range GICV_DIR INTID** — rated Moderate by Red Hat.
