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:
- In igen6_probe(), igen6_pvt will be allocated with kzalloc()
- In igen6_register_mci(), mci->pvt_info will point to
&igen6_pvt->imc[mc]
During rmmod:
- In mci_release() in edac_mc.c, it will kfree(mci->pvt_info)
- In igen6_remove(), it will kfree(igen6_pvt);
Fix this issue by setting mci->pvt_info to NULL to avoid the double
kfree.
