{
    "lastseen": "",
    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/mana: Validate rx_hash_key_len\n\nSashiko points out that rx_hash_key_len comes from a uAPI structure and is\nblindly passed to memcpy, allowing the userspace to trash kernel\nmemory. Bounds check it so the memcpy cannot overflow.",
