Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> RDMA/mana: Validate rx_hash_key_len<br /> <br /> Sashiko points out that rx_hash_key_len comes from a uAPI structure and is<br /> blindly passed to memcpy, allowing the userspace to trash kernel<br /> memory. Bounds check it so the memcpy cannot overflow.
