CVE-2024-56708
7.8
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
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.
