BigDL Software Advisory
| Intel ID: | INTEL-SA-01553 |
|---|---|
| Advisory Category: | Software |
| Impact of vulnerability: | Escalation of Privilege |
| Severity rating: | MEDIUM |
| Original release: | 11/10/2026 |
| Last revised: | 11/10/2026 |
Summary:
Potential security vulnerabilities for some BigDL software may allow escalation of privilege. Intel is not releasing updates to mitigate this potential vulnerability and has issued a Product Discontinuation Notice for BigDL software.
Vulnerability Details:
CVEID: CVE-2026-52899
Description: Deserialization of untrusted data for some BigDL software before version 2.5.0b1 within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with an unauthenticated user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via network access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (low) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
CVSS Base Score 4.0: 6.9 Medium
CVSS Vector 4.0: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N
CVEID: CVE-2026-20703
Description: Protection mechanism failure for some BigDL before version 2.4.0 within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with a privileged user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires passive user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
CVSS Base Score 4.0: 5.4 Medium
CVSS Vector 4.0: CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
CVEID: CVE-2026-56440
Description: Improper input validation for some BigDL before version 2.5.0b1 within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with an unauthenticated user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires active user interaction. The potential vulnerability may impact the confidentiality (low), integrity (low) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
CVSS Base Score 4.0: 4.6 Medium
CVSS Vector 4.0: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N
Affected Products:
BigDL software all versions.
Recommendation:
Intel has issued a Product Discontinuation Notice for BigDL software. As of the date of this advisory, the BigDL software is not supported with any additional functional, security, or other updates. Intel recommends that users of the BigDL software uninstall it or discontinue use as soon as possible.

Intel would like to thank Dan Aridor, Muhammad Fadilullah Dzaki and Lakshmi Vignesh S (CVE-2026-56440), Nguyễn Khánh - MBBANK (CVE-2026-52899), Lakshmi Vignesh S and Shrinivasan Sekar (CVE-2026-20703) for reporting these issues.
Intel, and nearly the entire technology industry, follows a disclosure practice called Coordinated Disclosure, under which a cybersecurity vulnerability is generally publicly disclosed only after mitigations are available.
Intel researchers conduct offensive security reviews as part of our Secure Development Lifecycle (SDL) framework. This includes using advanced analysis and AI-assisted diagnostic tools to simulate adversary capabilities and proactively address potential vulnerabilities prior to external exposure, limiting attacker advantage.
