Descriptions

A memory leak in the mlx5_fw_fatal_reporter_dump() function in drivers/net/ethernet/mellanox/mlx5/core/health.c in the Linux kernel before 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering mlx5_crdump_collect() failures, aka CID-c7ed6d0183d5.

Una pérdida de memoria en la función mlx5_fw_fatal_reporter_dump() en el archivo drivers/net/ethernet/mellanox/mlx5/core/health.c en el kernel de Linux versiones anteriores a la versión 5.3.11, permite a atacantes causar una denegación de servicio (consumo de memoria) al desencadenar fallos de la función mlx5_crdump_collect(), también se conoce como CID-c7ed6d0183d5.

A flaw was found in the way the Mellanox 5th generation network adapters (ConnectX series) core driver in the Linux kernel handled resource cleanup in the mlx5_fw_fatal_reporter_dump function. This flaw allows an attacker with the ability to trigger errors in the mlx5_crdump_collect function to crash the system.
