CVE-2024-58034

HighCVSS 7.8/10Last modified Jun 17, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

memory: tegra20-emc: fix an OF node reference bug in tegra_emc_find_node_by_ram_code()

As of_find_node_by_name() release the reference of the argument device node, tegra_emc_find_node_by_ram_code() 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 for_each_child_of_node() macro and of_get_child_by_name() instead of of_find_node_by_name() to simplify the code.

This bug was found by an experimental verification tool that I am developing.

[krzysztof: applied v1, adjust the commit msg to incorporate v2 parts]
