CVE-2024-58034

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> memory: tegra20-emc: fix an OF node reference bug in tegra_emc_find_node_by_ram_code()<br /> <br /> As of_find_node_by_name() release the reference of the argument device<br /> node, tegra_emc_find_node_by_ram_code() releases some device nodes while<br /> still in use, resulting in possible UAFs. According to the bindings and<br /> the in-tree DTS files, the "emc-tables" node is always device&amp;#39;s child<br /> node with the property "nvidia,use-ram-code", and the "lpddr2" node is a<br /> child of the "emc-tables" node. Thus utilize the<br /> for_each_child_of_node() macro and of_get_child_by_name() instead of<br /> of_find_node_by_name() to simplify the code.<br /> <br /> This bug was found by an experimental verification tool that I am<br /> developing.<br /> <br /> [krzysztof: applied v1, adjust the commit msg to incorporate v2 parts]
