CVE-2020-10722: Integer Overflow
First published: Tue Apr 28 2020(Updated: )
A vulnerability was found in DPDK through version 18.11, vhost_user_set_log_base() is a message handler that is called to handle the VHOST_USER_SET_LOG_BASE message. Its payload contains a 64 bit size and offset. Both are added up and used as a size when calling mmap(). There is no integer overflow check. If an integer overflow occurs a smaller memory map would be created than requested. Since the returned mapping is mapped as writable and used for logging, it seems highly likely that memory corruption can occur.
