Описание
In the Linux kernel, the following vulnerability has been resolved: igb: Fix potential invalid memory access in igb_init_module() The pci_register_driver() can fail and when this happened, the dca_notifier needs to be unregistered, otherwise the dca_notifier can be called when igb fails to install, resulting to invalid memory access.
Отчет
Bug could happen during error path and during device registration. The security impact is limited.
Меры по смягчению последствий
To mitigate this issue, prevent module igb from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically.
