Attack conditions (Source advisory, CVSS 3.1): Local · Low privileges required · No user interaction required

What an attacker can do

A malicious user can modify fields like num_sge or sge entries while the kernel is processing the WQE, leading to out-of-bounds reads in rxe_resp_check_length() and copy_data(). Source advisory’s CVSS 3.1 assessment (base score 7.8/10) rates confidentiality, integrity and availability impact as high.
