CVE-2024-26858

A vulnerability was found in the mlx5e_txwqe_complete() function in the Linux kernel. The CPU or compiler may reorder two of the functions: mlx5e_ptp_metadata_map_put() and mlx5e_ptpsq_track_metadata(), and a situation could arise where metadata tracking occurs before the metadata map is fully populated. This could lead to a NULL pointer dereference which can cause crashes.
