Docker Desktop broken with 6.18 kernel — netlink ABI incompatibilityHi @benhillis, thanks for flagging the opportunity to report 6.18-related issues here. SummaryDocker Desktop (WSL2 backend) fails to start its This affects both custom-built 6.18 kernels and (expected) the official 6.18.26.1 kernel shipped in WSL 2.7.5. Root causeDocker Desktop ships precompiled LinuxKit binaries (including This is a kernel ABI break at the netlink level — no kernel config or module-loading strategy can work around it. Docker needs to recompile their LinuxKit binaries for 6.18+ compatibility. Reproduction steps
ImpactAnyone upgrading to WSL 2.7.5 (or using a custom 6.18 kernel) who relies on Docker Desktop will have Docker completely broken with no user-side workaround. Possible mitigations

Quick follow-up: the Docker Desktop versions I tested are 4.69, 4.71, 4.73.0, and 4.73.1 — all exhibit the same netlink ABI crash with the 6.18 kernel. So this isn't specific to one Docker release; it's any current version shipping LinuxKit binaries compiled against 6.6.x headers. |

v2.7.5 doesn't work for me. I can't install a distro after updating from v2.7.3 to it and I can't run one that's fine with v2.7.3 - I just get: I've done a "Repair" from the v2.7.5 EDIT: v2.7.5 doesn't work when Windows 11 is running virtually (in Linux, KVM) ; it's working as expected on a Lenovo laptop running Windows 11 directly. I've never seen this phenomenon in many years of using WSL. |
