CVE-2024-58034: memory: tegra20-emc: fix an OF node reference bug in tegra_emc_find_node_by_ram_code()
In the Linux kernel, the following vulnerability has been resolved:
memory: tegra20-emc: fix an OF node reference bug in tegraemcfindnodebyramcode()
As offindnodebyname() release the reference of the argument device node, tegraemcfindnodebyramcode() releases some device nodes while still in use, resulting in possible UAFs. According to the bindings and the in-tree DTS files, the "emc-tables" node is always device's child node with the property "nvidia,use-ram-code", and the "lpddr2" node is a child of the "emc-tables" node. Thus utilize the foreachchildofnode() macro and ofgetchildbyname() instead of offindnodebyname() to simplify the code.
This bug was found by an experimental verification tool that I am developing.
