CVE-2024-26917: scsi: Revert "scsi: fcoe: Fix potential deadlock on &fip->ctlr_lock"
First published: Wed Apr 17 2024(Updated: )
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.
