CVE-2023-52456

A flaw was found in the UART driver handling RS485 communication in the Linux Kernel when an unexpected closure of the TTY port occurs, such as during a userland application crash. In this scenario, the imxuartshutdown function disables the UART interface and the Transmission Complete TC interrup...
