Description

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: fix a double-free in arfs_create_groups When `in` allocated by kvzalloc fails, arfs_create_groups will free ft->g and return an error. However, arfs_create_table, the only caller of arfs_create_groups, will hold this error and call to mlx5e_destroy_flow_table, in which the ft->g will be freed again. A double-free vulnerability was found in the `arfs_create_groups` function in the Linux kernel's `net/mlx5e` driver. This issue could lead to memory corruption or a system crash if exploited, as freeing the same memory twice may cause undefined behavior.
