In the Linux kernel, the following vulnerability has been resolved:

RDMA/srpt: fix integer overflow in immediate data length check

imm_buf->len is a user-controlled uint32_t received from the network.

Adding it to imm_data_offset without overflow checking allows a

malicious initiator to send len=0xFFFFFFFF, causing req_size to wrap

around to a small value, bypassing the bounds check, and subsequently

passing a ~4GB length to sg_init_one().

Use check_add_overflow() to detect wrapping before the comparison. (NVD)
