Overview

CVE-2024-50025 is a medium-severity vulnerability affecting linux linux_kernel. It was published on October 21, 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:

scsi: fnic: Move flush_work initialization out of if block

After commit 379a58caa199 ("scsi: fnic: Move fnic_fnic_flush_tx() to a

work queue"), it can happen that a work item is sent to an uninitialized

work queue. This may has the effect that the item being queued is never

actually queued, and any further actions depending on it will not

proceed.

The following warning is observed while the fnic driver is loaded:
