Dozens of Lenovo s flagship ThinkPad models are vulnerable to bugs ranging in severity from low to high. Two of the flaws are tied to industry-wide security bulletins, while a medium-severity flaw affects only Lenovo laptops but remains unpatched. The most severe of the three bugs is a Bluetooth vulnerability that could allow a nearby attacker to perform an information-disclosure or an escalation-of-privileges attack, according to a U.S. Computer Emergency Readiness Team (US CERT) description.
