How to fix?

There is no fixed version for RHEL:7 kernel-bootwrapper.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-bootwrapper package and not the kernel-bootwrapper package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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

scsi: Revert "scsi: fcoe: Fix potential deadlock on &fip->ctlr_lock"

This reverts commit 1a1975551943f681772720f639ff42fbaa746212.

This commit causes interrupts to be lost for FCoE devices, since it changed sping locks from "bh" to "irqsave".

Instead, a work queue should be used, and will be addressed in a separate commit.
