CVE-2026-74397

CVE-2026-74397 affects the Linux kernel mlx5 driver (IB/mlx5). The issue arises in mlx5_ib_alloc_transport_domain() which can leak a transport domain if mlx5_ib_enable_lb() fails; a fix deallocates the TD on error, returns 0 explicitly in the no-loopback-capability success branch, and moves dev-&...
