Descriptions
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: fix a potential double-free in fs_any_create_groups
When kcalloc() for ft->g succeeds but kvzalloc() for in fails,
fs_any_create_groups() will free ft->g. However, its caller
fs_any_create_table() will free ft->g again through calling
mlx5e_destroy_flow_table(), which will lead to a double-free.
Fix this by setting ft->g to NULL in fs_any_create_groups().
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net/mlx5e: corrige una posible double free en fs_any_create_groups Cuando kcalloc() para ft->g tiene éxito pero kvzalloc() para in falla, fs_any_create_groups() liberará ft-> gramo. Sin embargo, su llamador fs_any_create_table() liberará ft->g nuevamente llamando a mlx5e_destroy_flow_table(), lo que conducirá a un double free. Solucione este problema configurando ft->g en NULL en fs_any_create_groups().
