This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

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

RDMA/mana: Validate rx_hash_key_len

Sashiko points out that rx_hash_key_len comes from a uAPI structure and is

blindly passed to memcpy, allowing the userspace to trash kernel

memory. Bounds check it so the memcpy cannot overflow.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. 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.
