Fix it by simply passing the number of VPEs allocated, which is the index of the loop iterating over the VPEs.

Affected files ============== The file(s) affected by this issue are: drivers/irqchip/irq-gic-v3-its.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/7d39992d45acd6f2d6b2f62389c55b61fb3d486b https://git.kernel.org/stable/c/5701e8bff314c155e7afdc467b1e0389d86853d0 https://git.kernel.org/stable/c/42d3711c23781045e7a5cd28536c774b9a66d20b https://git.kernel.org/stable/c/568662e37f927e3dc3e475f3ff7cf4ab7719c5e7 https://git.kernel.org/stable/c/e0c1c2e5da19685a20557a50f10c6aa4fa26aa84 https://git.kernel.org/stable/c/280bef512933b2dda01d681d8cbe499b98fc5bdd
