      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nvsock: fix buffer size clamping order\n\nIn vsock_update_buffer_size(), the buffer size was being clamped to the\nmaximum first, and then to the minimum. If a user sets a minimum buffer\nsize larger than the maximum, the minimum check overrides the maximum\ncheck, inverting the constraint.\n\nThis breaks the intended socket memory boundaries by allowing the\nvsk->buffer_size to grow beyond the configured vsk->buffer_max_size.\n\nFix this by checking the minimum first, and then the maximum. This\nensures the buffer size never exceeds the buffer_max_size.",
