## Overview

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

scsi: fnic: Fix crash in fnic_wq_cmpl_handler when FDMI times out

When both the RHBA and RPA FDMI requests time out, fnic reuses a frame to
send ABTS for each of them. On send completion, this causes an attempt to
free the same frame twice that leads to a crash.

Fix crash by allocating separate frames for RHBA and RPA, and modify ABTS
logic accordingly.

Tested by checking MDS for FDMI information.

Tested by using instrumented driver to:

 - Drop PLOGI response
 - Drop RHBA response
 - Drop RPA response
 - Drop RHBA and RPA response
 - Drop PLOGI response + ABTS response
 - Drop RHBA response + ABTS response
 - Drop RPA response + ABTS response
 - Drop RHBA and RPA response + ABTS response for both of them

## Affected

- `linux_kernel >= 6.14, < 6.15.5`
- `linux_kernel = 6.16`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.15.5`
