Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a deadlock in the tx statemachine when using the serial port as an RS485 port. This occurs when the TTY port is closed during a transmission, causing the interface to become useless. The
imx uart stop tx function now checks for incomplete transmission and whether TC interrupts are enabled before bailing to be retriggered, ensuring the state machine handling is reached and properly set to WAIT AFTER SEND.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
