5.5 · MEDIUMOverview
CVE-2021-46914 is a medium-severity vulnerability affecting linux linux_kernel. It was published on February 27, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
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.
ixgbe 0000:17:00.1: disabling already-disabled device
