CVE-2026-74717

A denial-of-service vulnerability in the Linux kernel's net/mlx5 firmware tracer (fw_tracer). The tracer creation function can return either NULL or ERR_PTR on failure, but the core dump logic (mlx5_fw_tracer_trigger_core_dump_general) does not check for ERR_PTR and dereferences it, leading to a ...
