CVE-2026-46145

EUVD-2026-32772
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.
