What to Know

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. (NVD)

What to Do

Monitor Linux's and Red Hat's web pages for any future patch releases.
