CVE-2025-40136

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> crypto: hisilicon/qm - request reserved interrupt for virtual function<br /> <br /> The device interrupt vector 3 is an error interrupt for<br /> physical function and a reserved interrupt for virtual function.<br /> However, the driver has not registered the reserved interrupt for<br /> virtual function. When allocating interrupts, the number of interrupts<br /> is allocated based on powers of two, which includes this interrupt.<br /> When the system enables GICv4 and the virtual function passthrough<br /> to the virtual machine, releasing the interrupt in the driver<br /> triggers a warning.<br /> <br /> The WARNING report is:<br /> WARNING: CPU: 62 PID: 14889 at arch/arm64/kvm/vgic/vgic-its.c:852 its_free_ite+0x94/0xb4<br /> <br /> Therefore, register a reserved interrupt for VF and set the<br /> IRQF_NO_AUTOEN flag to avoid that warning.
