CVE-2022-50019 Details
Description
In the Linux kernel, the following vulnerability has been resolved: tty: serial: Fix refcount leak bug in ucc_uart.c In soc_info(), of_find_node_by_type() will return a node pointer with refcount incremented. We should use of_node_put() when it is not used anymore.
A refcount leak vulnerability has been identified in the Linux kernel's UART driver, specifically within the 'ucc_uart.c' file. The issue arises in the 'soc_info()' function, where 'of_find_node_by_type()' returns a node pointer with an incremented refcount. The vulnerability occurs because the refcount is not properly decremented when the node is no longer needed, leading to a memory management issue.
