Details

The issue is described here:

https://seclists.org/oss-sec/2019/q2/86

The fix (supposedly) consists of applying these two patches, which have not been merged by upstream yet:

https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/patch/net/ipv4/udp_offload.c?id=21f1b8a6636c4dbde4aa1ec0343f42eaf653ffcc

This probably also affects other flavors of the 5.0 kernel, like linux-hardened and linux-zen. linux-lts should not be affected, since the vulnerable code was only introduced in Linux 5.0.
This task depends upon

Damn, typo in the bug report title - can somebody please change "linux >=5.0.11" to "linux =<5.0.11"?

"GRO packet of death" was fixed 3 months ago in 5.0.13 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.0.13

Does it close the case?
