Description Alex 2023-03-29 12:50:42 UTC 
A flaw in the Linux Kernel found. In the Linux kernel before 5.15.13, drivers/net/ethernet/mellanox/mlx5/core/steering/dr_domain.c misinterprets the mlx5_get_uars_page return value (expects it to be NULL in the error case, whereas it is actually an error pointer).
