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.
Affected configurations
• linux linux kernel (>= 5.11 < 5.15.174)
• linux linux kernel (>= 5.16 < 6.1.120)
• linux linux kernel (>= 6.2 < 6.6.64)
• linux linux kernel (>= 6.7 < 6.11.11)
• linux linux kernel (>= 6.12 < 6.12.2)
