Bug Description

[Impact]
KASAN detected a use-after-free condition, which could lead to memory corruption or a crash.

[Test Case]
Rebuild kernel w/ CONFIG_KASAN=y, look for errors in dmesg.

[Fix]
3a39a12ad364a net: hns: fix KASAN: use-after-free in hns_nic_net_xmit_hw()

[Regression Risk]
Fix is restricted to the hns driver, which is the driver for the nics on the Hi1616 SoC. Regressions would therefore be limited to platforms using this SoC, such as the HiSilicon D05 board.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-cosmic' to 'verification-done-cosmic'. If the problem still exists, change the tag 'verification-needed-cosmic' to 'verification-failed-cosmic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
