Descriptions

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.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: net/mlx5e: corregido un double free en arfs_create_groups Cuando falla `in` asignado por kvzalloc, arfs_create_groups liberará ft->g y devolverá un error. Sin embargo, arfs_create_table, el único llamador de arfs_create_groups, mantendrá este error y llamará a mlx5e_destroy_flow_table, en el que ft->g se liberará nuevamente.

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.
