CVE-2026-46030 Details
Description
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.
A memory leak vulnerability has been identified in the Linux kernel's EDAC Versalnet driver. The issue arises in the 'mc_probe()' function, where the 'of_parse_phandle()' call returns a device node reference that is not properly released, leading to a memory leak. This vulnerability affects the Linux kernel stable tree.
The vulnerability has been fixed in the Linux kernel stable tree. Users can download the patched version from the Linux kernel Git repository.
