Severity CVSS v4.0:
Pending analysis
Type:
CWE-416
Use After Free

Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
octeon_ep: cancel queued works in probe error path<br />
<br />
If it fails to get the devices&#39;s MAC address, octep_probe exits while<br />
leaving the delayed work intr_poll_task queued. When the work later<br />
runs, it&#39;s a use after free.<br />
<br />
Move the cancelation of intr_poll_task from octep_remove into<br />
octep_device_cleanup. This does not change anything in the octep_remove<br />
flow, but octep_device_cleanup is called also in the octep_probe error<br />
path, where the cancelation is needed.<br />
<br />
Note that the cancelation of ctrl_mbox_task has to follow<br />
intr_poll_task&#39;s, because the ctrl_mbox_task may be queued by<br />
intr_poll_task.
