Title:
i40e driver: CVE-2016-8105 X710 buffer overflow cause denial of
service
Status in linux package in Ubuntu:
Incomplete
Bug description:
See the detailed issue here: https://www.intel.com/content/www/us/en
/security-center/advisory/intel-sa-00069.html
On Feb 27, 2017 Intel has revealed this security issue that when the
rx buffer is full and not being processed, the buffer will hang and
never reset.
Recently we found this issue in 18.04.2, we have a shared port setup
on BMC and host network, where bmc and host share the same nic rx
queue, when the host kernel panic, the rx queue gradually become full
and eventually cause DOS on BMC.
I have verified the issue affects both 18.04-ga (i40e 2.1.14-k) and
18.04-hwe (i40e 2.3.5), I compile the latest i40e driver 2.7.29 and
the issue is gone. Intel should had the driver fixed after version
2.3.6.
The current i40e driver needs patch.
