[SRU][F/J/M][PATCH 0/1] Fix UBSAN: array-index-out-of-bounds in drivers/net/hyperv/netvsc.c

[Guoqing Jiang]

SRU Justification

BugLink: https://bugs.launchpad.net/bugs/2058477

[Impact]
error message "UBSAN: array-index-out-of-bounds in drivers/net/hyperv/netvsc.c:1446:41" appears
multiple times during boot for a Hyper-V environment.

[Fix]
Clean cherry-pick commit bb9b0e46b84 for Focal, Jammy and Mantic.

[Test case]
check the dmesg to see if there is the error message "UBSAN: array-index-out-of-bounds"

[Regression Potential]
DPDK which processes netvsc packets, so it might incompatible with ancient DPDK, but modern DPDK
had already used flexible array member.
