In the Linux kernel, the following vulnerability has been resolved:
ixgbe: fix unbalanced device enable/disable in suspend/resume
pci_disable_device() called in __ixgbe_shutdown() decreases dev->enable_cnt by 1. pci_enable_device_mem() which increases dev->enable_cnt by 1, was removed from ixgbe_resume() in commit 6f82b2558735 ("ixgbe: use generic power management"). This caused unbalanced increase/decrease. So add pci_enable_device_mem() back.
Fix the following call trace.
