CVE-2026-46030
In the Linux kernel, the following vulnerability has been resolved: EDAC/versalnet: Fix device_node leak in mc_probe() of_parse_phandle() returns a device_node reference that must be released with of_node_put(). The original code never freed r5_core_node on any exit path, causing a memory leak. Fix this by using the automatic cleanup attribute __free(device_node) which ensures of_node_put() is called when the variable goes out of scope.
Affected versions
Linux kernel versions
6.18
and later are affected. Fixed in
6.18.27,
7.0.4,
7.1-rc1
and their respective stable series.
