Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> usb: typec: ucsi: Handle incorrect num_connectors capability<br /> <br /> The UCSI spec states that the num_connectors field is 7 bits, and the<br /> 8th bit is reserved and should be set to zero.<br /> Some buggy FW has been known to set this bit, and it can lead to a<br /> system not booting.<br /> Flag that the FW is not behaving correctly, and auto-fix the value<br /> so that the system boots correctly.<br /> <br /> Found on Lenovo P1 G8 during Linux enablement program. The FW will<br /> be fixed, but seemed worth addressing in case it hit platforms that<br /> aren&amp;#39;t officially Linux supported.
