Privilege Escalation Vulnerability in BigDL by Intel

CVE-2026-20703

What is CVE-2026-20703?

The identified vulnerability in BigDL prior to version 2.4.0 represents a significant protection mechanism failure. Unprivileged software adversaries, leveraging a privileged user environment, can exploit this flaw through a low-complexity attack. This scenario allows for an escalation of privilege, which may necessitate only local access. Attackers can potentially bypass security without specialized internal knowledge, requiring minimal passive interaction from users. As a consequence, this vulnerability poses risks to the confidentiality, integrity, and availability of the affected systems, which may lead to severe security implications.
