Details

In the Linux kernel, the following vulnerability has been resolved:

ixgbe: fix unbalanced device enable/disable in suspend/resume

pcidisabledevice() called in __ixgbeshutdown() decreases dev->enablecnt by 1. pcienabledevicemem() which increases dev->enablecnt by 1, was removed from ixgberesume() in commit 6f82b2558735 ("ixgbe: use generic power management"). This caused unbalanced increase/decrease. So add pcienabledevicemem() back.

Fix the following call trace.
