- Summary
- RDMA/rxe: Fix responder length checking for UD request packets
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Fix responder length checking for UD request packets
According to the IBA specification: If a UD request packet is detected with an invalid length, the request shall be an invalid request and it shall be silently dropped by the responder. The responder then waits for a new request packet.
commit 689c5421bfe0 ("RDMA/rxe: Fix incorrect responder length checking") defers responder length check for UD QPs in function
copy_data. But it introduces a regression issue for UD QPs.When the packet size is too large to fit in the receive buffer.
copy_datawill return error code -EINVAL. Thensend_data_inwill return RESPSTERRMALFORMED_WQE. UD QP will transfer into ERROR state. - References
