CVE-2025-39973

In the Linux kernel, the following vulnerability has been resolved:

i40e: add validation for ring_len param

The `ring_len` parameter provided by the virtual function (VF)

is assigned directly to the hardware memory context (HMC) without

any validation.

To address this, introduce an upper boundary check for both Tx and Rx

queue lengths. The maximum number of descriptors supported by the

hardware is 8k-32.

Additionally, enforce alignment constraints: Tx rings must be a multiple

of 8, and Rx rings must be a multiple of 32.
