CVE-2025-21651
Estado: ModificadaMedia (4.7)—
In the Linux kernel, the following vulnerability has been resolved:
net: hns3: don't auto enable misc vector
Currently, there is a time window between misc irq enabled and service task inited. If an interrupte is reported at this time, it will cause warning like below:
So don't auto enable misc vector when request irq..
