EDAC/igen6: Avoid segmentation fault on module unload

CVE-2024-56708

Description

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

EDAC/igen6: Avoid segmentation fault on module unload

The segmentation fault happens because:

During modprobe: 1. In igen6_probe(), igen6_pvt will be allocated with kzalloc() 2. In igen6_register_mci(), mci->pvt_info will point to &igen6_pvt->imc[mc]

During rmmod: 1. In mci_release() in edac_mc.c, it will kfree(mci->pvt_info) 2. In igen6_remove(), it will kfree(igen6_pvt);

Fix this issue by setting mci->pvt_info to NULL to avoid the double kfree.
