Technical description

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

net: xilinx: axienet: Add error handling for RX metadata pointer retrieval

Add proper error checking for dmaengine_desc_get_metadata_ptr() which

can return an error pointer and lead to potential crashes or undefined

behaviour if the pointer retrieval fails.

Properly handle the error by unmapping DMA buffer, freeing the skb and

returning early to prevent further processing with invalid data.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
