CVE-2026-43199 Linux内核mlx5e驱动原子调度漏洞

/* * PoC Concept for CVE-2026-43199 * This snippet demonstrates the context of the bug. * Triggering this requires specific IPsec configuration on Mellanox NICs. */ #include <linux/workqueue.h> // Simulated vulnerable function context void mlx5e_ipsec_init_macs_vulnerable(void) { // In atomic context (workqueue) // Calling this function leads to scheduling while atomic // mlx5_query_mac_address(dev, mac); } // To trigger: // 1. Configure IPsec policy on a system with mlx5e driver. // 2. Trigger an event that calls mlx5e_ipsec_handle_event. // 3. Kernel will panic with 'scheduling while atomic'.
