CVE ID : CVE-2024-56708
Published : Dec. 28, 2024, 10:15 a.m. | 2 hours, 8 minutes ago
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.
Severity: 0.0 | NA
