CVE-2026-46145 is an out-of-bounds write vulnerability in the Linux kernel RDMA/mana component. The driver accepts rx_hash_key_len from a userspace-controlled uAPI structure and passes it to memcpy without validating its bounds. An oversized length can overflow the destination buffer and corrupt kernel memory. The fix validates rx_hash_key_len before the copy.
