Description

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 products

• Linux kernel: from 6.18 before 6.18.32; from 6.19 before 7.0.9; 7.1-rc1, 7.1-rc2 — fixed in 6.18.32, 7.0.9

How to fix

Upgrade to a fixed version: Linux kernel 6.18.32, 7.0.9. Check the vendor advisory for mitigations.
