Impact

A vulnerability in Lenovo tablets permits an attacker who has physical possession of the device to bypass authentication controls and gain unauthorized access. The flaw is a potential authentication bypass, identified as CWE-288, that could allow an attacker to operate the tablet without valid credentials.

Affected Systems

The issue affects a broad range of Lenovo tablet models, including Idea Tab Pro (TB373FU), Idea Tab/ Tab K11 Gen 2 in several configurations such as TB336FU, TB336FU/TB336ZU, TB336ZU, and TB336ZU/TB336FU, Legion Tab 8.8 (TB321FU), Tab Extreme (TB570FU, TB570ZU, TB570ZU/TB570FU), Tab K11 (TB330FUP, TB330XUP), Tab K11 Plus (TB352FU, TB352XU), Tab K11 Plus LTE ROW (TB352XU) and Tab K11 Plus WIFI ROW (TB352FU), Tab K9 (TB305FU, TB305XU), Tab M10 5G (TB360ZU), Tab M11 (TB330FU, TB330FU/TB330XU, TB330XU), Tab One (TB305FU, TB305XU), Tab P12 (TB370FU, TB370FU/TB372FU, TB372FU), Tab Plus (TB351FU), Tab with Clear/Folio Case (TB311FU, TB311FU/TB311XU, TB311XU), Yoga Tab (TB710FU), and Yoga Tab Plus (TB520FU).

Risk and Exploitability

The vulnerability carries a CVSS score of 7, indicating high severity for the affected devices. The EPSS score of <1% suggests a very low probability of exploitation, and the lack of an official KEV listing indicates that widespread exploitation has not yet been reported. The attack likely requires physical access to the device, making it relevant for environments where tablet possession is not tightly controlled. Without the vendor’s firmware update, the risk of unauthorized device usage remains significant.
