CVE-2020-10722

A vulnerability was found in DPDK versions 18.05 and above. A missing check for an integer overflow in vhost_user_set_log_base() could result in a smaller memory map than requested, possibly allowing memory corruption.

6.7 (Medium)


                        
                          CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H

CWE-190 - Integer Overflow or Wraparound

CVE-2020-10723

A memory corruption issue was found in DPDK versions 17.05 and above. This flaw is caused by an integer truncation on the index of a payload. Under certain circumstances, the index (a UInt) is copied and truncated into a uint16, which can lead to out of bound indexing and possible memory corruption.

6.7 (Medium)


                        
                          CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H

CWE-190 - Integer Overflow or Wraparound

CVE-2020-10724

A vulnerability was found in DPDK versions 18.11 and above. The vhost-crypto library code is missing validations for user-supplied values, potentially allowing an information leak through an out-of-bounds memory read.

5.1 (Medium)


                        
                          CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:H

CWE-125 - Out-of-bounds Read
