CVE-2026-74397

CVE-2026-74397 describes a Linux kernel issue in the mlx5/IB stack: mlx5_ib_alloc_transport_domain() allocates a transport domain that can leak if mlx5_ib_enable_lb() fails. The mitigation enforces deallocation of the TD on error, returns 0 in the no-loopback success path, and relocates dev->l...
