Linux Distros Unpatched Vulnerability : CVE-2024-50025

medium Nessus Plugin ID 230787

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - 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: kernel: WARNING: CPU: 11 PID:
 0 at ../kernel/workqueue.c:1524 __queue_work+0x373/0x410 kernel: <IRQ> kernel: queue_work_on+0x3a/0x50 kernel: fnic_wq_copy_cmpl_handler+0x54a/0x730 [fnic 62fbff0c42e7fb825c60a55cde2fb91facb2ed24] kernel:

 common_interrupt+0x58/0xa0 kernel: </IRQ> It has been observed that this may break the rediscovery of Fibre Channel devices after a temporary fabric failure. This patch fixes it by moving the work queue initialization out of an if block in fnic_probe(). (CVE-2024-50025)

Note that Nessus relies on the presence of the package as reported by the vendor.
