NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-modules-extra-matched package and not the kernel-modules-extra-matched package as distributed by RHEL.

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.
