Title
RDMA/uverbs: Prevent integer overflow issue
Summary
In the Linux kernel, the following vulnerability has been resolved: RDMA/uverbs: Prevent integer overflow issue In the expression "cmd.wqe_size * cmd.wr_count", both variables are u32 values that come from the user so the multiplication can lead to integer wrapping. Then we pass the result to uverbs_request_next_ptr() which also could potentially wrap. The "cmd.sge_count * sizeof(struct ib_uverbs_sge)" multiplication can also overflow on 32bit systems although it's fine on 64bit systems. This patch does two things. First, I've re-arranged the condition in uverbs_request_next_ptr() so that the use controlled variable "len" is on one side of the comparison by itself without any math. Then I've modified all the callers to use size_mul() for the multiplications.

Then we pass the result to uverbs_request_next_ptr() which also\\ncould potentially wrap.  The \\\"cmd.sge_count * sizeof(struct ib_uverbs_sge)\\\"\\nmultiplication can also overflow on 32bit systems although it\u0027s fine on\\n64bit systems.\\n\\nThis patch does two things.  First, I\u0027ve re-arranged the condition in\\nuverbs_request_next_ptr() so that the use controlled variable \\\"len\\\" is on\\none side of the comparison by itself without any math.  Then I\u0027ve modified\\nall the callers to use size_mul() for the multiplications.\"},{\"lang\":\"es\",\"value\":\"En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: RDMA/uverbs: Evitar problema de desbordamiento de enteros En la expresi\u00f3n \\\"cmd.wqe_size * cmd.wr_count\\\", ambas variables son valores u32 que provienen del usuario, por lo que la multiplicaci\u00f3n puede provocar un encapsulamiento de enteros. Luego, pasamos el resultado a uverbs_request_next_ptr(), que tambi\u00e9n podr\u00eda potencialmente encapsularse.

Este parche hace dos cosas. Primero, he reorganizado la condici\u00f3n en uverbs_request_next_ptr() para que la variable controlada por uso \\\"len\\\" est\u00e9 en un lado de la comparaci\u00f3n por s\u00ed misma sin ning\u00fan c\u00e1lculo.
