UBUNTU-CVE-2026-68139

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Use sender devcom for MPV master-up After PCIe DPC recovery, mlx5 reloads the affected functions and replays multiport affiliation events. In the reported failure, the first relevant device error was: pcieport...

CVE-2026-68139

CVE-2026-68139 affects the Linux kernel mlx5e/MPV path. After PCIe DPC recovery, mlx5 reloads affected PCIe functions and replays multiport affiliation events; during resume, an RDMA multiport binding replay triggers an MPV_DEVCOM_MASTER_UP. The host panics with a NULL pointer dereference in mlx5...
