[SRU][F][PATCH 0/2] CVE-2021-47070

[Bethany Jamison]

[Impact]

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

 uio_hv_generic: Fix another memory leak in error handling paths

 Memory allocated by 'vmbus_alloc_ring()' at the beginning of the probe
 function is never freed in the error handling path.

 Add the missing 'vmbus_free_ring()' call.

 Note that it is already freed in the .remove function.

[Fix]

Mantic:	not-affected
Jammy:	not-affected
Focal:	Fix and prereq commits were cleanly cherry-picked.
Bionic:	not-affected
Xenial:	not-affected
Trusty: not-affected

[Test Case]

Compile and boot tested.

[Where problems could occur]

This fix affects those who use the hyper-v UIO driver, issues with the
fix would be visible with loss of memory resources including slower
performance and potentially a future system crash.
