Vulnerability from github – Published: 2024-02-27 09:31 – Updated: 2024-04-10 15:30

Details

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.
