CVE-2026-46221
In the Linux kernel, the following vulnerability has been resolved: EDAC/versalnet: Fix device name memory leak The device name allocated via kzalloc() in init_one_mc() is assigned to dev->init_name but never freed on the normal removal path. device_register() copies init_name and then sets dev->init_name to NULL, so the name pointer becomes unreachable from the device. Thus leaking memory. Use a stack-local char array instead of using kzalloc() for name.
Affected versions
Linux kernel versions
6.18
and later are affected. Fixed in
6.18.32,
